Cats are wonderful creatures. When we understand them, we can use that information to make them happier. Here are five things to do for your cat today – and a bonus one to work on over time.


1. Make time to play with your cat


11% of cats have no toys, according to one study (Howell et al 2016).

But the average cat has 7 toys, and toy mice are the most popular. (Strickler and Shull 2014)

Even if your cat has lots of toys of their own, they still like it when their human plays with them. 64% of the owners in Strickler and Shull’s study played with their cat twice a day, but playtime typically lasted 5 or 10 minutes. Amongst people who played with their cat for at least 5 minutes instead of just 1 minute, there were fewer behaviour problems.

But your cat would probably like an even longer play time.

Have you ever felt that when you are moving a toy for your cat, they seem to be hunting it? This is because play satisfies the cat’s predatory instincts.

John Bradshaw PhD, author of Cat Sense and other best-selling books on pets, told NPR that “The research that we've done suggests that [play] it's almost indistinguishable, that everything that a cat does when it's playing seems to be a part of its normal hunting behavior.”

So when a cat plays, it’s not so much about the cat being sociable with you, it’s really about hunting.

This means they like toys that are like prey in some way – maybe they are furry or have feathers or are mouse-sized or squeak like a mouse or are long so the cat can kick their back legs against it. And cats would like you to move it as if it is real prey for them to chase.

5 things to do for your cat today to provide enrichment, play time and hiding places. A beautiful kitten sits with its paws crossed.


Every cat is an individual, so experiment with different types of toys and different ways of moving them to see what makes your cat engage in play.

And remember that cats can get bored of toys, so you can put some of them away in a cat’s toy box and rotate the toys that are available. (If you have a cat like my tortoiseshell, she will learn to open the box and pick her own toys!).

You might find that multiple sessions of 5 - 10 minutes works best, but you can experiment and see what your cat likes.

Free-ranging cats spend a large part of each day hunting for food, which shows just how important hunting behaviour is to a cat. Strickler and Shull suggest that cats would probably like it if an individual play session lasts for longer than 10 minutes; 30 minutes is the typical length of a time a free-ranging cat spends on a single hunt (although only some of that time would be active chase as the mouse has first to be found). Play keeps your cat active and satisfies that predatory instinct.

So make time to play with your cat!


2. Give your cat a food toy


Another way to engage your cat’s hunting instinct is through the use of food toys. These provide valuable enrichment to our feline friends.

There are many food toys available, including balls with holes in that the cat has to roll to make treats fall out, the mouse-shaped no bowl, containers that have to be tipped like the Trixie Mad Scientist, and things the cat has to paw at to get the treats out like the Trixie 5-in-1 Activity Center.

There are food toys for every level of feline ability. If your cat is new to food toys, start with something easy so they don’t get frustrated trying to get at the food. You may also need to use particularly tasty treats to get their interest. Over time, you can make the toys more difficult, and use them to feed all meals instead of providing ‘free’ food in a bowl.

You can also hide the toys around the house so the cat has to hunt for them to get started.


The great thing about food toys is that although there are some fantastic ones on the market, you can also make them for free. For example, make a hole in a cardboard tube, stick paper over one end, put food inside, paper over the other end, and let your cat figure out how to get the food out of the hole.

Only 5% of cats have food puzzle toys according to a survey of the enrichment people provide for their cats (Alho et al 2016).

Food puzzle toys can help to resolve feline behaviour problems because they provide environmental enrichment that can reduce stress and make the cat more active. (Dantas et al 2016)

Food toys are great for cats because they make them work for their food – completing another part of the predatory sequence.


3. Make sure your cat has nice hiding places


As well as thinking about cats evolving as solitary hunters of prey, we have to remember that cats themselves are prey animals. Which means cats like places they can hide and feel safe.

This is especially important if you have a fearful cat – the kind that runs to hide when people come over to the house.

But all cats need places to hide. In fact, a recent study of shelter cats’ use of a hiding box and a separate perch found the hiding box was much preferred, so much so that it may be considered a basic need for cats (Ellis et al 2017b).

The kind of hiding place that cats prefer is cat-sized, secluded, and often high up from the ground. It’s a place in which they can feel safe.

Examples of safe hiding places include a cardboard box (e.g. a regular cardboard box laying on its side, or a box specially designed for cats), a perch with a lip or a box to go in on a cat tree, a cat cube or cocoon (many types are available commercially), the cat carrier (if the cat likes it), a space on a shelf, or in a cupboard or wardrobe where the cat has access.

So do a quick survey of the places that are available to your cat as hiding places. Are they in busy parts of the house or does the cat also have hiding places in quieter rooms? Are they cat sized, or are they a bit too big? If your cat has outside access, do they also have safe hiding places in your yard or garden?

You can make existing hiding places more comfortable by adding a fleecy blanket or towel for the cat to curl up on.

And if you think your cat might not have enough spaces, see about providing some extra ones. It may be as simple as giving them a cardboard box and putting it on its side, or putting it upside down with a hole cut out for them to go in and out.


4. Use scents as enrichment


Did you know that your cat has an amazing nose, and on top of that they also have a vomeronasal organ that detects pheromones – chemical signals that have meaning to cats? This means that scent is far more important in your cat’s life than you realize.

When your cat rubs its head on you or the furniture, it is leaving pheromones behind. You may even notice a little brown mark on the wall where your cat rubs often. Don’t clean it up! Or at least don’t clean all of them up at once. Those familiar chemical signals that the cat is depositing help them to feel safe and secure.

Everyone is familiar with catnip toys, but there are other scents that many cats like too, so you could try valerian, silver vine or honeysuckle and see if your cat responds to those. Almost all cats will visibly respond to at least one of these scents.

You can find valerian in some cat toys, silver vine is available as a stick or powder, and honeysuckle as blocks of wood of various sizes. They may not be in your local pet store, so you may have to look for them online.

You can buy catnip that is mixed with other scents such as lavender, so if your cat likes catnip this is another way to provide different scents as enrichment.

In fact a recent study found that although only some cats respond to catnip by rolling around, other cats do respond, just in a passive way such as being in a Sphinx position or being less active and miaowing less (Espin-Iturbe et al 2017).

Another way to provide scent as enrichment if you have an indoor cat is to open the window for them to let them smell the air from outside. Obviously, do this in a safe way so they can’t escape – and remember that screens are not necessarily cat-safe. But you only need to open the window a chink to let the outside smells in.


5. Clean the litter tray


Did you notice how I saved the most glamorous one til last?!!

I know what you're thinking. The other four are all fun, and this one... not so much.

But the litter tray is a serious matter for cats. Many house-soiling issues are due to problems with the litter tray (but if your cat suddenly starts making a mess in the house, it’s important to see a vet in case a medical issue is the cause). It’s an important issue because inappropriate toileting behaviour is a common reason for cats to be surrendered to animal shelters.

26% of pet cat owners clean their litter box once a day, but 11% only clean it once a week and 5% less frequently than that (Howell et al 2016). So there is plenty of scope for improvement amongst the average cat owner. And it really doesn't take long.

Cats prefer a clean litter box. It’s not so much the smell they object to, but the presence of urine or faeces that is visually unappealing and physically in the way (Ellis et al 2017).

Cats will typically still use a litter box they are not very happy with, but signs they are not so keen on it include being hesitant to go in it, going in and then out of it, keeping a paw out of it while they eliminate, and spending a long time over elimination (McGowan et al 2017). This study also found that cats may hold their urine if they are not happy with their litter box, making them vulnerable to urinary tract infections.

So you should scoop your litter tray every day, but preferably twice a day, and clean the litter tray thoroughly once a week.


6. Bonus: Teach your cat to like their carrier


This is a bonus item because it is not something you can achieve in a day, especially if your cat is already scared of their carrier. Which they might be if it only ever predicts visits to the vet.

But one thing you can do today is get the carrier out, have a look at it and see if it’s suitable, leave it out somewhere so it becomes a normal thing – and make a plan to teach your cat to like it.

The best kind of carrier is one that is secure but where the top half can be detached from the bottom half. This means that at the vet, you can simply remove the top and the vet can examine the cat in the bottom of the carrier. Some cats will feel safer like this than if they have to come completely out of the carrier. (See more tips on how to help cats at the vet).

If the carrier always means an unpleasant trip to the vet, you can’t really blame a cat for not liking it. So you need to break that association. If your cat is terrified of the carrier you already have, you might find it best to start afresh with a new carrier.

Put a nice fleecy blanket or towel in the bottom so it is nice and cosy. And then leave it somewhere in the house where it will become a familiar thing. You might need to prop the door open so it can’t accidentally close behind the cat when they go in.

You can leave treats inside it to encourage your cat to go in. But for many cats even this will be too scary, so you may have to start by leaving treats in the general vicinity of the carrier. Once the cat is relaxed and comfortable collecting those treats, you can put treats a bit closer, until eventually the cat will approach the carrier.

This is a slow process. For a full explanation of how to teach your cat to like their carrier, I recommend this post by Sarah Ellis PhD. (You might like to read my interview with Dr. Sarah Ellis for more tips on training your cat).


Summary of tips for your cat


So there you have it – five things to do for your cat today, and a sixth one to work on over time. Play with your cat, use food toys, provide safe hiding places, use scent as enrichment, and remember to scoop the litter tray! Then start thinking about how to teach your cat to like their carrier.

These tips will provide enrichment for your cat, help your cat be more active and help them to feel safe and secure.

Of course, every cat is an individual and has their own preferences as all cat lovers know well. In the comments, let me know which are your cat’s favourite toys, and where is your cat’s favourite hiding place?

Shelter Cats Like a Box to Hide In

Cats like somewhere to hide - and research shows a cardboard box can be the simple solution.

A cat hides in a cardboard box - important enrichment for cats because they like places to hide


How do we know what types of enrichment are most important to cats? A new study by Dr. Jacklyn Ellis (University of Prince Edward Island) et al tests shelter cats’ preferences. The results show the importance of a simple cardboard box for kitty cats.


What is environmental enrichment for cats?


Environmental enrichment involves adding something to the cat’s environment that is good for its welfare. Enrichment can be especially important for cats in shelters since the environment is stressful for them, away from their familiar home and with the presence of unknown cats and people, and perhaps with dogs in earshot too. But it's important for our cats at home too.

There are many ways to provide enrichment for cats, including vertical space, olfactory enrichment, food and even cognitive enrichment with clicker training.


How do we know what cats like?


How do we know which types of enrichment cats like best? For example, we know that cats like to be high up, and we also know that cats like to hide, but which is most important to them?

One way to find out is to investigate whether a particular enrichment leads to better physical and behavioural health, as with Gourkow and Phillips (2016) study of clicker training shelter cats.

Another way is to give cats a choice between enrichment items, and see where they choose to spend their time. The study by Dr. Jacklyn Ellis et al uses this method to see which of three types of enrichment shelter cats prefer.

This is a choice test, in which the animal is placed in one chamber with access to other compartments that contain different items, to see which one(s) they access the most. It’s also possible to do a motivational test to see how hard an animal will work to access a particular compartment. These methods have been used with a wide range of animals, including goldfish to see if they prefer real or artificial plants (answer: goldfish like both real and artificial plants).


The study of shelter cats and enrichment choices


The current study aimed to investigate which type(s) of enrichment shelter cats prefer out of a choice between a hiding box, a shelf to perch on, and a prey-like toy (the Mouse Chaser). Since we already know that cats like to hide, to perch in high up places, and to play with toys, it’s interesting to see which one they like best.

26 domestic cats from an animal shelter took part in groups of 3 at a time. On average, the cats had been at the shelter for 6 days. While they took part in the study the cats were housed in a lab that was set up with three choice chambers (one per cat). The cats could not see the other cats, although they could hear them.

The choice chamber consisted of a central space that contained the cat’s food and litter, with four compartments leading off. One was empty as a control, while the other three compartments contained the hiding box, perch, and toy. Access to the compartments was via a cat flap, and after time to acclimate to the central space the cats were taught how to use the cat flaps using wet food, treats or petting as rewards. Once they’d got the hang of that, the experiment itself began.

The cat flaps were set up so that a record was automatically made every time the flap was opened. The researchers measured how often each compartment was accessed over a period of 7 days, and how much time the cats spent in there.


Results of the study


The results show that although there were no differences in how often each chamber was accessed, the cats spent significantly more time in the compartment with the hiding box.  This suggests the hiding box was important to them.

There was also an effect of light, with compartments being visited more often during light hours than dark, and in particular between 8am and midday, suggesting the cats were more active during this time. However light and dark did not affect the amount of time spent per compartment. Individual cats differed a lot in terms of how much time they spent perching on the shelf.


There were no effects of age, sex or whether the cat was a stray or a surrender on the frequency of visits to the compartments. However, cats that had been strays spent less time in the control (empty) compartment than cats that had been surrendered by their owners. The researchers suggest this may be because stray cats either prefer to avoid empty spaces, or to spend more time in close proximity to their resources (given they are used to having to find them for themselves).

The researchers raise the question of whether the hiding box was enrichment or in fact actually a necessity. Some scientists say enrichment is about providing something that brings positive welfare benefits, rather than prevents poor welfare.

The scientists write,
“These authors may contend that the much greater allocation of time to the hiding box may be evidence that not providing an opportunity for these individuals to hide is failing to cater to their basic needs.”
The layout of the room was such that only one of the choice chambers gave cats a view of whether or not a person was approaching; the other chambers could be accessed from more than one angle. In this chamber, the cats tended to spend more time in the compartment from where they could see someone approaching, suggesting they value time with a person.

Over time cats may change their preferences, and as seen with the perches in this study, each cat is an individual. Since only one toy was used in the study, it may be that different types of toy, having a variety of toys, and/or toys that involve interaction with a human might be preferred by particular cats.

The scientists conclude that,
“Although the frequency in which the cats visited each compartment did not differ, they allocated more of their time to the compartment with a box that provided a hiding opportunity. This may be because hiding satisfies a basic need for cats housed short-term in caged conditions.”
Although the study took place in a lab, which may be less stressful than the shelter, it shows that hiding places were still very important to the cats.


Hiding places for shelter cats and owned cats


Many shelters already provide a hiding space for cats. One example is the BCSPCA’s Hide Perch and Go, which provides a hiding space, a perching space and can be used to transport the cat. Another is the Feline Fort from Cats Protection that includes a step and table as well as hiding place and is easy to disinfect.

The research is only about shelter cats and not owned cats, but it has implications for cats at home, who benefit from hiding spaces too. Providing a safe space is one of the five pillars of a healthy feline environment (Ellis et al 2013). Cats are prey animals and can be taken by coyotes etc, and as solitary hunters if they got injured it would have serious consequences for future food acquisition. So cats feel safer when they have places to hide, which may be enclosed, high up, and in a quiet area.

Why not take a look around your home and see which spaces are available for your cat to hide in. Under the bed and under the settee can be good hiding places, but they are still quite large areas, and cats prefer to have smaller cat-sized hiding places where they can feel more enclosed.

The hiding place used in this study is easy to replicate at home, since it was a cardboard box with a hole cut in one side to provide access. Other options include cat trees with enclosed hiding spaces, cat tunnels, cat carriers, or even access to a suitable shelf or cupboard in your house (so long as they can't get trapped there). Leaving the cat carrier out and making it a nice comfy hiding space also has benefits when it comes to taking your cat to the vet.

If you have multiple cats in your home, each one needs access to hiding places without having to compete with the other cats.

The full paper is open access and can be read via the link below.

What kind of hiding places does your cat spend time in?

It's Not Just Catnip: Olfactory Enrichment for Cats

The olfactory enrichment cats love but you’ve (probably) never heard of.

A euphoric cat rolling on a catnip plant - but some cats also respond to silver vine, honeysuckle, and valerian


A new study tests domestic cats with four different types of olfactory enrichment: catnip, silver vine, Tatarian honeysuckle and valerian. Tigers and bobcats were also tested. The results show almost all domestic cats love at least one of these.

These compounds are safe and not addictive, meaning owners have an easy way to provide enrichment to their cats (provided they can get hold of them).

First author, Dr. Sebastiaan Bol told me in an email,
“This research gave us insight in how many cats in the USA go crazy for catnip and plants that can have a similar effect on cats. Catnip was loved by many, but so was silver vine, a plant that is very popular in Japan, stinky valerian root and the wood of Tatarian honeysuckle. Sadly, about 1 out of every 3 cats doesn't like catnip. It's not a choice; it's genetically determined. The good news is that this study demonstrates that most of these cats WILL LOVE one or more of the other, SAFE, plant materials that were just mentioned.  
“These plant materials are a lot of fun for your cat at home, but they may also be helpful when socializing scared cats, for trap-neuter-return programs, training (e.g. redirecting scratching behavior) and possibly even for reducing stress during for example medical procedures (e.g. giving a pill), transportation and (medical) boarding. So much research that needs to be done!  
“The results from our small survey learned us that most veterinarians in the USA, including ones specialized in cats, do not know about the existence and effects on cats of these plants. This is why we love to reach out to people who care about the well-being of cats.  
“Finally, also for cats who DO like catnip, it can be super exciting to receive something new that they may like. If you enjoy drinking a glass of red wine, that doesn't mean you won't like a glass of champagne, does it? It probably depends on the moment. It's the same for cats. The best thing about being a cat in this particular case is that you don't have to worry about becoming an alcoholic or getting a hangover; all these plant materials come without any known negative side effects.” 

So whether or not your cat likes catnip, it’s worth giving these a try.

Sebastiaan Bol says his cats love silver vine, as you can see from the photo of Zappa enjoying her silver vine stick.

"Pretty much every day I see how much two of our six cats love the silver vine wood sticks. Multiple wood sticks are available to them all the time, but they really seem to pick their moment. It's adorable to watch and it makes me so happy to see them enjoy it so much."

The study tested 100 domestic cats with all four of these compounds. The cats were mostly moggies and they included cats at a sanctuary, waiting for adoption at a rehoming centre, at a cat-friendly veterinary practice and cats in their own homes. Five of the cats were adopted before completing the study, so the final sample was 95 cats.

The compounds were presented in two ways: in a sock, or on a piece of carpet. If the cat did not notice the arrival of the compound, it was moved one time to see if it would attract their attention, but cats were not chased with the items – it was up to them whether to interact with it or not. An empty sock was used as a control, but the person coding the responses did know which substance it was.

You have probably seen the classic kitty response to catnip, which includes licking, sniffing, drooling, rubbing the head or chin on the catnip, rolling, and raking (bunny-kicking the back legs). But not all cats respond to catnip, and this study found that about a third of cats did not respond to it.

Silver vine was a favourite, with 80% of the cats responding to silver vine. About half of the cats responded to valerian, and half to Tatarian honeysuckle. In fact, only six of the cats did not respond to any of the smells.

Young and old cats were equally likely to respond. The scientists also found similar responses in cats considered friendly, shy, or somewhere in between. This suggests that this olfactory enrichment is suitable for all cats.

The study was conducted because there are anecdotal reports of cats responding to these substances (and to a fifth one, Indian nettle root, that was not tested). In Japan, silver vine is popular for cats and is known as matatabi. However, the scientists asked 38 vets and 6 vet techs who specialize in cats if they knew about this, and almost all said no. So you can be forgiven for not knowing about it too.

The chemical which causes the effect in catnip is called nepetalactone. Silver vine contains six compounds that are similar, and one is also found in valerian.


Silver vine is available in different forms, including wood sticks, powder, normal fruit, and fruit galls (where midge larvae have matured). The scientists found cats were more responsive to the fruit galls than the normal fruit. Unfortunately this makes it more difficult to commercially prepare silver vine on a large scale, since not very much is known about the silver vine gall midge and it also requires another plant as part of its life cycle. If you are looking to try it with your cat, the powder (which is the powder of the silver vine fruit galls) is probably the best place to start.

Tatarian honeysuckle is available as sticks or as blocks of wood. It will last forever, although you may need to wash it from time to time (after your cat has drooled on it a lot). If your cat stops responding to it, you can shave a bit of wood off to give it a fresh edge again.

Valerian root is available in some cat toys.


A cat lies on a catnip plant - but many cats respond to the smell of silver vine, honeysuckle or valerian too. Great enrichment for your cat!


Catnip, of course, is available as plants for your garden, as a dried herb (including with additional scents), and in many different cat toys.

The scientists tested catnip and silver vine on nine tigers at Big Cat Rescue, where keepers gave it to the animals. One tiger had a little interest in catnip, but the others were not interested. Four tigers were not interested in silver vine – and five of them took an active dislike to it. So it does not make good enrichment for tigers.

They also tested bobcats. Four bobcats responded to silver vine, and one to catnip, and their response was similar to that of the domestic cats. If you take a look at the paper (which is open access), you can see a photo of a bobcat rubbing her chin and cheeks on a paper bag that contains silver vine.

The video below, which was made several years ago, shows some of the cats at Big Cat Rescue responding to catnip.



A chemical analysis of all four substances shows the concentration of the chemical compounds which cats are probably responding to.

All four of these substances cause euphoria in at least some cats, with most cats responding to silver vine. So it is worth trying them out to see if they make your cat happy too.

The scientists conclude that “Olfactory enrichment using silver vine, Tatarian honeysuckle or valerian root may, similar to catnip, be an effective means to improve the quality of life for cats. Nearly all cats responded positively to at least one of these plants.”

The paper is open access, and you can follow the first author on twitter and Facebook.

Have you tried any of these alternatives to catnip with your cat?

Vertical Space is Good Enrichment for Cats

Cats make good use of added vertical space, study shows.


A tabby cat relaxes on a shelf


A study by Emma Desforges (Waltham Centre for Pet Nutrition) et al finds that adding a vertical screen is good enrichment for cats. And while the study used cats that live at the Waltham research centre, the results suggest pet cats could benefit too.

The scientists took an Ikea bookcase called Kallax in which the shelves are subdivided. They put half the backing on one side and half on the other, so that some shelves faced one way and the rest the other way (8 spaces arranged 2 x 4 per side). Then they put it in the middle of a room.

If you’re thinking crazy cat lady organizer, you’re not far off, but this version is taller.

They observed the cats for set time intervals for two days before the screen was added, four days while it was there, and two days after it was removed.

Cats used the screen and spent more time off the ground when it was there, even though they already had some shelves around the walls of the room. The spaces allowed them to get away from other cats if they wanted.


There were some effects of time of day, but in general the cats showed fewer unfriendly behaviours when the screen was there.

When the screen was taken away, unfriendly behaviours increased.

And although the screen gave cats the chance to hide from each other, they still engaged in the same number of friendly behaviours before and during the screen phase.

The scientists write, 
“In summary, exploiting the unused vertical space by the addition of stand-alone shelving should be considered a valuable resource for the cat by increasing useable space and reducing agonistic interactions, with the caveat that the shelving remains a permanent fixture or for rolling replacement of enrichment objects with alternative forms of similar value.”

In other words, once you’ve given them some shelves, don’t take them away without having a replacement because they will miss them.

29 cats took part in the study. They live in four different groups at the Waltham pet nutrition centre. Enrichment is especially important for captive cats like this.

But indoor cats could benefit too. These days, many people keep their cats indoors because of concerns about the risks of being outside (coyotes and cars, for example). Using vertical height, as in this study, is one way to adapt the indoor environment for cats.

This study suggests it would be particularly important in a multi-cat household, but individual cats will also benefit from the opportunities to use vertical space and have nice vantage points from which to survey the room.

You do not have to rush out to Ikea, although the Kallax shelving does look like it’s designed to provide cubby holes for cats. Perhaps you already have some bookshelves and can clear space on them so your cats can use the shelves. Other options include shelves mounted on the walls, vertical scratching posts affixed to walls with a shelf at the top for cats to climb up to, or tall cat trees for cats to perch in.

If you’re feeling creative, Ikeahackers have lots of suggestions for re-modelling Ikea furniture for cats, and Ikea now have cat inserts for the Kallax shelving.

Your Cat Would Like Food Puzzle Toys

Food puzzles will help satisfy your cat’s hunting instinct, but most cats are missing out.


The benefits of food puzzle toys as enrichment for cats, like the food ball this cat is playing with


A new paper on food puzzle toys for cats has plenty of ideas to get everyone started on these wonderful enrichment items. The research, led by Mikel Delgado (University of California, Berkeley; Feline Minds), combines a review of the scientific literature on food toys as feline enrichment with practical tips gained from the authors’ work as feline behaviour practitioners.

Food puzzles are toys that make your cat do some work to get the food out of them. Maybe they have to stick their paw in and pick pieces of food out, or maybe they roll it around with their nose or paw to make food fall out of the holes. There are many different types of food toys, some of which stay in one place and others that the cat has to move around.

“It's a great way to give your cat something to do to keep them busy and get them doing what a predator is supposed to do... Working for their food!!” Mikel Delgado told me. “It's great for their brains and body!

“A bonus is that it's really fun to watch your cat play with a food puzzle!”

Most cats miss out on food toys


A study of enrichment for cats found that only 5% of cats have food toys. An earlier study of how owners play with their cats found just 1% of cats have food toys, and only 0.5% of owners hide food for their cat to find.

The benefits of food puzzle toys as enrichment for cats - this ginger cat is dreaming of them


If your cat is one of those missing out, read on to find out why these feline scientists say you should give food puzzles a try.

The benefits of food puzzle toys for cats


Food puzzles make cats engage in part of their natural predation sequence – getting food. This has many benefits, according to the report, including encouraging cats to be more active, reducing stress levels, and making them be less demanding of their owners.

If your cat is overweight or obese, then food puzzle toys can help cats to lose weight. In some cases, introducing food puzzle toys has also helped to resolve litter tray indiscretions (N.B. If your cat is toileting outside their litter tray, they must see a vet to solve any medical issues first).

The report provides several case studies in which food puzzles have been all or part of the solution to feline behaviour problems.


For example, a 3 year old neutered male cat was biting his owners, sometimes without warning. This was considered due to frustration. Introducing a combination of food puzzles led to some immediate improvement. Six months later, the aggressive behaviour had completely stopped.

Food puzzles are also suitable for multi-cat homes, although each cat should have their own toy.

How to get started with food puzzle toys


We all know cats can be finicky. You should expect to try several types of food toys in order to find ones your cat loves. Note that’s plural – your aim is to find (or make) several different food puzzles for your cat.

Some cats that are used to having food freely available at all times may go on strike when they first find out they are now expected to work for their food. Not eating can be very dangerous for cats, so it’s important to make the toys accessible.

Early on, they have to be very easy. You can increase the difficulty later, once your cat has got the hang of it.

“Initially, obtaining food from the food puzzle needs to be as easy as obtaining food from the food bowl,” write the scientists. “This means that the cat should have to do very little work for food at first. The puzzle should be filled as much as possible, and should have several, large holes to allow food to fall out easily. The puzzle should roll with little manipulation. For stationary puzzles, cups or reservoirs should be overflowing.”

Mixing some treats in with the cat’s regular food at first may help them to be interested in it. For puzzles that move, you can roll it around to show them how it works, and it will also help to present it on a surface where it will move easily (rather than carpet as that will make it harder; your cat can build up to this if you like).

To begin with, you should still feed your cat some of their daily food in their bowl. Over time, once your cat has become adept at the food toy, you can reduce the amount in the bowl until they are working for all of their food.

Your cat really will like food puzzle toys


It seems that every cat can benefit from food toys and there are few, if any, downsides. A common reason they are not more widely used, according to the report, is that cat guardians think their cat will not be interested in them. Reassuringly, they say every cat they have worked with has learned to use food puzzles – even those with special needs. So why not give them a try?

Trouble-shooting problems


If your cat seems to be frustrated with the toy, you may need to make it easier for them. Remember that it should be overflowing with food at the beginning. If your cat is what the report calls a 'slow starter', you can hide a small portion of food somewhere for them to find. If it’s canned food, you can put a spoonful in a cup cake holder or on a little saucer to stop it from marking your furniture.

If your cat seems bored, you can always make the toy more difficult (making sure you don’t go too far and make it too difficult). Some toys are adjustable to different difficulty levels. You can also try new toys.

The paper also suggests filling a small food toy and putting it inside a larger one, which seems like a fiendish level of difficulty for expert cats.

If you have a dog, you will need to think of a way to keep the dog from eating the cat’s food. You could use a pet gate to keep the dog away, or feed the cats in a room the dog doesn’t have access to. You may already be doing this to keep the dog away from the cat’s food bowl anyway. And you can, of course, give your dog their own food enrichment toys.

Buy food puzzle toys or make them for your cat – it’s your choice


These days, there are lots of food puzzle toys on the market. It’s also very easy to make your own.

You can make a very simple toy by cutting a hole in a cardboard tube (e.g. from toilet roll), putting food inside and sealing both ends. Remember to make it a large hole at the beginning so that it’s easy for your cat. The report includes a photo of this and several other purchased and home-made food puzzles.

Two of the authors of this paper, Mikel Delgado and Ingrid Johnson, have a website that reviews food puzzles for cats. It has plenty of ideas for do-it-yourself toys too and is an excellent resource for anyone interested in providing more enrichment for their feline friend. I love this example that only requires a brown paper bag.





One of their reviews features a 15-year old toothless, arthritic, three-legged cat enjoying using a toy called the Dog Tornado by Nina Ottoson. Food puzzles are suitable for all cats.

The full paper is open access at the link below. It’s an interesting read and includes photos of food toys, including some DIY options, as well as lots of tips for introducing your cat to food puzzles.

What is the Best Enrichment for Your Ferret?

New research finds out how hard ferrets will work to access different types of enrichment.

Ferrets' preferences for hammocks, foraging toys, and tunnels

Providing environmental enrichment is an important part of good animal welfare. For example, cats whose owners play with them regularly have fewer behaviour problems. We know a lot about enrichment for cats. What about ferrets? Earlier research has shown that more play behaviours are reported when there are more enrichment items. But although ferrets are a popular pet, we know little about their personal preferences. A new study by Marsinah Reijgwart (Utrecht University) et al has important tips for ferret owners.

Of course, you can’t just say, “Ferret, what would you like?” One way of testing how much animals value certain things is to put a door between them and the item. By gradually increasing the difficulty of opening the door, we can see how much effort they will put in to reach the item, and therefore how much it is worth to them. This is known as a motivational test, or consumer demand test.

It has even been tried successfully with goldfish, in a study that found goldfish like both real and artificial plants as enrichment.

Reijgwart et al ran a similar experiment with ferrets, in which doors were successively made heavier to find out how hard ferrets would try to reach various enrichment chambers. There were 7 chambers, six containing different types of enrichment, and one that was empty (the control). The corridor contained food, drinking water (via a nipple), and windows into each chamber so the ferrets could see what was inside. Every chamber had a one-way unweighted door to give them access back to the corridor.

As well as measuring the maximum weight of the door that ferrets would push, the scientists also looked at how long the ferret spent interacting with the enrichment item.

Seven spayed female ferrets, approximately one year old, took part. The results show the ferrets like:

  • Sleeping enrichment. This was the most important to them. Given a choice of sleeping items, they preferred a hammock to sleep in rather than a Savic Cocoon.
  • Water bowls. They preferred a large water bowl rather than a small one.
  • Social enrichment. They liked to have a ferret friend to snuggle with.
  • Foraging enrichment. They liked to have foraging toys.
  • Tunnels. They spent more time in the opaque flexible tunnel rather than the see-through rigid tunnel. Some ferrets liked tunnels a lot, while others were less interested in them.
  • As for balls, they preferred a ball with a bell to a golf ball or ferret ball.

Ferrets used the items in multiple ways. For example, although the hammock was used for sleeping in, it was also a tug toy. Food obtained from the foraging toys was often eaten immediately, but sometimes the toys were taken away and stored elsewhere (such as in the Savic Coccoon).

The ferrets in this study live in the laboratory. I asked Marsinah Reijgwart what the implications are for people who keep ferrets as pets. Despite limitations, there are important lessons about the kinds of enrichment that should be provided for pet ferrets.

“To start, I have to make some remarks on the limitations with regards to generalizing the results to pet ferrets,” she told me in an email. “The research question (enrichment preferences for laboratory ferrets) has influenced the choices I have made for the enrichments that I have tested. For instance, I have not looked at the ferrets’ motivation for playing or cuddling with a person. Also, intact or male ferrets or ferrets of a different age may have different preferences.

"Next to that, I have tested the ferrets individually, so they might like certain items more or less than I have seen in this test when ferrets can enjoy enrichments together (or with a human). Additionally, life in a research facility is very different from life as a pet, which means that the preferences for enrichment can differ. For instance, my ferrets were housed at a constant temperature and only had limited time to spend with people.

“With my research, I have tried to draw general conclusions on enrichment preferences for the average one-year old female ovariectomized laboratory ferret. You cannot generalize these results to other ferrets, as their preferences might be different.

"This being said, I do think some of the results can be very informative for ferret owners.

“First of all, my ferrets pushed open a door that weighed 1450 grams (150% of their own body weight!) to reach a room with three types of sleeping enrichments: a hammock, a flexible plastic bucket on its side and a Savic Cocoon. In a previous study I have showed that this is the maximum weight the ferrets are able to push: at higher weights the ferrets still tried, but were not able to open the door.

“This, together with the obvious preference for sleeping in the hammock when the ferrets made it into the room, makes it safe to say: give your ferret a hammock!! However, while this is a new discovery for laboratory animal science, ferret owners have been aware of this preference for a while, so I doubt if there is a pet ferret out there without a hammock of some sort.

“Secondly, my ferrets pushed 1075 grams to drink out of a water bowl, while water from a bottle was freely available. They did not touch the water bottle in the days that they gained access to the water bowls. As I don’t think that this is a preference that will be different for pet ferrets, I would advise ferret owners to give their ferret a water bowl. As we all know, ferrets will play with the water and make a mess. Therefore, I would advise to also give your ferrets a water bottle, just in case they are thirsty but have an empty or dirty water bowl.

“Thirdly, my ferrets pushed 950 grams to eat from foraging enrichment while the same food was freely available in a bowl. Think about it: ferrets worked (pushed 950 grams of weight) to work (push around the ball or flip the tumbler) for food while this wasn’t necessary to fulfil their nutritional needs.

“This shows that, as is the case for other animals, you should not make life too easy for your ferret. There are many commercially available foraging toys for cats that ferrets can enjoy just as much. If you are a bit creative, you can save some money by looking up DIY foraging toys online. Mentally stimulating your ferret for just a few minutes can be very enriching!


Enrichment for ferrets

“For the other enrichments that I have tested (balls, tunnels, ferrets), it is more difficult to draw conclusions for pet ferrets.

“My ferrets were not very motivated to play with the balls, but it is possible that they would like them more when playing together with another ferret or a person.

“The tunnels are a special case, as one ferret pushed to her maximal abilities to get to the tunnels, while other ferrets stopped bothering at very low weights. A tunnel is most probably an enrichment that some ferrets really enjoy playing with, while others would rather play with something else. Not everyone likes the same things, it is up to you as a ferret owner to find out what your ferret enjoys.

“Finally, I am not able to draw conclusions about the big question that many ferret owners have: should ferrets be kept alone or together? My ferrets were separated by wired mesh and pushed quite high weights (995 grams) to visit the other ferrets. When a ferret reached the others, she would snuggle up to the mesh and sleep as close together to the others as possible.

“In a follow-up study where ferrets shared an enclosure, I saw that they often chose to jump into a hammock to huddle up with the other ferrets, while there was also an empty hammock available. But remember: these were ovariectomized female ferrets that were about one year old.

“So as with the tunnels: it is up to you as a ferret owner to see if your ferret fares well with ferret companions or whether he/she prefers to be alone.”
