Tag Archives: food puzzles

I’m a big fan of food puzzles as an enrichment choice for cats. As natural predators, cats have evolved to work for their food. We brought them inside, handed them a bowl of food, and took their jobs away. At least that’s the way I like to think about it.

For those of you who aren’t familiar with food puzzles, check out the website Food Puzzles for Cats (disclaimer, I am co-owner of the site, but I get no financial benefits from it!). Food puzzles are like other types of foraging enrichments that are used with zoo and laboratory animals. They’re commonly used with pet dogs (e.g., the Kong), and more recently, food puzzles are increasingly being designed for cats. The idea is that an animal must forage for food – for cats this can range from a very simple activity (such as rolling a ball, allowing dry food to fall out) to more complex problem-solving (such as having to slide open doorways to access a well of food).

Previous studies of foraging devices have shown reduced aggression, increased activity, and reduced stereotypic behaviors in various species (including rats, monkeys, and horses). A new study, “Pilot study evaluating the impact of feeding method on overall activity of neutered indoor pet cats,” published last week in the Journal of Veterinary Behavior, evaluated the effect of food puzzles on activity levels in cats, utilizing accelerometer-based “activity collars” to measure movement.

Nineteen household cats participated in the study. Cats were either free-fed or fed once or twice per day. Using a crossover design, half of the cats were recorded for a week while feeding from their regular food bowls first, then recorded for a week while feeding from food puzzles; the other half of the cats were recorded using food puzzles first, then back to the bowl. Cats were given a week to acclimate to food puzzles and a week between conditions. All cats successfully transitioned to food puzzles to eat all their food. Feeding happened according to the previous feeding schedule for each cat (freely available food, or fed at one or two mealtimes per day).

Eleven of the cats used the Indoor Hunting Feeder which has five matching mouse-shaped puzzles, and the other eight cats used five different food puzzles made by PetSafe, including the SlimCat and Egg-Cersizer. Cats were assigned to puzzles based on an initial preference test.

Results showed no differences in activity levels based on how cats were eating (bowl vs puzzle). There was also no effect of puzzle type (Indoor Hunting Feeder vs PetSafe puzzles). In fact, the only real effect was that of age – older cats were less active in general.

The results may seem counter-intuitive, because after all, didn’t the cats have to move around to get the food out of the puzzles? Well there are a few possibilities:

  1. The cats have to move around to get the food out of the puzzles, but cats eating out of bowls compensate by moving around at other times – in either case, most of the cats in the study spent the majority of time inactive.
  2. The sample size was small, which might make it hard to tease apart differences between the bowl-feeders and puzzle-feeders. In statistical terms, we call this “underpowered.”
  3. Food puzzles really don’t increase activity (but perhaps they offer other benefits, such as slowing down feeding, and providing mental stimulation, warding off boredom or other problematic behaviors).
  4. The effect of food puzzles might be dependent on other factors (such as offering multiple types of enrichment).

I’m sure you can think of other explanations! Other studies have demonstrated an increase in anticipatory activity levels in cats when they are waiting for a meal, and that increasing the number of meals per day is a good way to increase activity in cats. Moreover, it would be great for someone to repeat this study with even more cats to increase statistical power, so that we can be certain the results are reliable.

So, if food puzzles DON’T increase activity levels in cats, should we just forget about ‘em? No way! As my co-authors and I reported a few years ago, we have seen many benefits of food puzzles when used with cats. I found it very encouraging that 100% of the cats in this study had no problem switching to puzzle feeding!

The benefits of food puzzles for cats may not be exactly what we thought in regard to activity levels (at least in the short term), but given the expansive research on the benefits of foraging enrichment for other species, I’d say the positive effects for cats most likely outweigh any failure to increase activity. That said, we might have to re-frame how we talk about those positive effects.

Yet here I am, packing my bags to head to DC for the conference of the American Association of Feline Practitioners. This year, one of the themes is feline behavior. That's right, 3 days of nothing but cat people and cat behavior!!! I'm really excited to hang with other cat peeps, including Kris Chandroo, Ingrid Johnson, Julie Hecht, Liz Bales, and Sarah Ellis (and I'm sure many more!). There will be plenty of talks from cat experts I'm excited to hear from!! I'll be tweeting from the conference, and hopefully a blog or two will happen in response!

Are cats just ruthless killers?

Letting your pet cats outdoors is a controversial topic (and apparently a cultural issue - here in the States, we lean more towards keeping them inside, and the Brits think we're nuts!).  Does it prevent behavior problems? Maybe -- but I have to say I have PLENTY of behavior clients with indoor/outdoor cats who fight with other cats, urinate or spray inside the house, or have aggression or attention seeking issues. So letting cats go outdoors is not the panacea for all feline behavioral ills as some might have you believe (I've previously written about some reasons to keep your cats indoors).

A new book "Cat Wars" might have you thinking that cats are the only source of avian woes (I've also written on this topic before for The Dodo - so don't forget about humans, squirrels, raccoons and other animals that make life rough on songbirds).

Bird Brilliance

Birds may use alligators as security guards -- previous studies show that birds that nest near alligator habitat produce more offspring. But a new study also showed that alligators near nesting birds were heartier, suggesting that the nesting birds may "pay" for this security service with a few babies that fall out of the nest...into the alligator's mouth. Read a summary here.

crowWhy are New Caledonian crows good at some tasks and not others? Is it the nature of the test? Researchers in New Zealand looked at the reasons that primates performed better on "self-control tasks" in a recent study that compared cognition across many species (hey I was one of the many authors of that study!) - could hands and experience with humans have an effect?

Meanwhile, a new paper explores the fact that corvids and parrots show cognitive abilities on par with primates, despite having a VERY different brain structure (which lacks the neocortex that is often considered responsible for "higher functions"). Summary here.

Do you play with your cat? How about every day? Be honest. I know most of you reading this are pretty lazy about playing with your cats (I can be too). You might even blame it on your cat…”Oh…he doesn't really like to play with toys,” “She liked to play when he was a kitten, but now that she’s older, she prefers to cuddle.” I've heard it all before and I know it’s a lie! Why? Because to cats, play should be practice for predation, and cats are natural-born killers who cannot resist the opportunity to pounce! This doesn't mean that the play is always fun for the human, who may or may not be particularly skilled at eliciting those killer behaviors in their cats. But we’ll get to that. First, let’s look at a recent study examining how play might influence the behavior of cats.

An Owner Survey of Toys, Activities and Behavior Problems in Indoor Cats” was recently published in the Journal of Veterinary Behavior. The study was a survey of 277 veterinary clients in Tennessee who were bringing their cats in for a veterinary visit (coming for anything besides a behavior problem rendered someone eligible to participate). The goal of the study was to examine just how much playtime owners give their cats, and how this might be correlated with behavior problems.

Owners were asked standard questions about their cats (such as if they were spayed/neutered, the cats’ sex and the like). The survey also asked owners if the cats eliminate outside of the litterbox, fight with other cats, and if they bite and scratch people. They were next asked how often and long they play with their cat, and what types of toys/activities they provide for their cats (e.g. balls, mice, stuffed toys, catnip, etc.). Finally, they asked participants if they talk to their veterinarian about any behavior problems their cat might be experiencing.

On the human side of things, all owners stated that they played with their cat at least once a month, with 64% claiming to play at least twice a day. Most owners played with their cat for 5-10 minutes at a time. The majority of people (78%) reported leaving toys out all the time for their cat.

On the cat side, we've got a lot of naughty kitties out there. Sixty-one percent of owners reported at least one undesirable behavior, with many cats displaying aggression toward people (36%), closely followed by urination outside the litterbox (24%) and aggression between cats in the home (21%). Of those owners with “problem children,” only half of them had mentioned the problem to their veterinarian.

Was playtime correlated with behavior problems? Maybe. The owners who played with their cats for longer periods of time reported fewer behavior problems (on average one behavior problem, compared to the 2.25 behavior problems reported by those who played with their cat for only one minute at a time). Behavior problems were strongly related to the sex of the cat, with male cats being more likely to have reported behavior issues, regardless of neuter status.

I do think we should interpret these results with some caution. First of all, we have a very small sample size of people (less than 10) who reported they only play with their cat for one minute at a time. These people may not be representative of a random sampling of people who don’t play much with their cat, and of course, we don’t know if the decreased play is the cause of the behavior problems, or the result (or because of something else altogether). We also don’t know if those who claimed to play with their cat for longer periods of time were being honest. Perhaps many of them only play for one minute as well, they just didn't feel like admitting it!

We also don’t know if people who bring their cats to the vet regularly are different from pet owners who do not. More than half of all pet cats do not get a yearly exam, due in large part to the fact that many cats are afraid of their cat carrier (a subject for another blog post!). So it’s possible that the cats represented in this survey are also somehow different from your average pet cat, for better or worse.

On behavior problems: it seems like a lot of cats are having them (more than reported in a previous study). Is this because people are making less time for their cats? Are more cats bored and indoors? (For the record, I advocate keeping cats indoors only, but it needs to be a loving, fun and stimulating environment!) They also didn't report whether age correlated with behavior problems, but I wonder if aggression toward humans is more prevalent in younger cats and kittens, with more of a playful/predatory bent, than the more fearful, defensive types of aggression problems seen in some cats.

Most people don’t mention behavior problems to their veterinarian, and while the authors suggest that veterinarians can be a resource for help, (no diss on vets, but…) I think it’s important to remember that most veterinarians do not get much (if any) training in cat behavior. In many veterinary programs, ONE multi-species behavior course is an elective, not a requirement (see here, here and here for examples of veterinary curricula). Many veterinarians admit they know little about behavior, while others may give outdated or just bad behavior advice!

That said, veterinarians are hopefully making progress on this end, and hopefully know of some resources for cat-owners that they can at least point them to (such as veterinary behaviorists, CAABS, the IAABC and Cats International) if they can’t answer a client's behavior-related questions! Because behavior issues are a major reason that cats are surrendered to shelters, it is important to intervene and provide assistance early!

This study reveals some valuable information about pet owners and the type of activities they provide for their cats and I have plenty of thoughts about the findings! This study found owners reporting even less playtime with cats than data from a study in 1997, where owners reported 20-40 minutes of daily play with their cats. Sadly, the current figure is probably not enough to meet most cats’ needs.

Furthermore, people need to expand their selection of toys and activities. In the current study, only 39% of owners reported using an interactive (“fishing pole”) toy with their cats. This is a travesty! Only NINE percent had a cat tree, four percent trained their cats to do tricks, and less than one percent provided food puzzles as enrichment for their cats. I’d say those are four “magic bullet” things that all cats owners can do to immediately improve their cats’ lives, and sadly, not many people are doing any of them.

So for those of you who might be cringing about the kitty care you are providing right now, I’m going to give you a few quick tips to make playtime easier for you and your cat:

Think like prey – get interactive (that means a toy with a stick that you move, not a toy you just toss across the room) toys that resemble birds, bugs and mice. Move them like birds, bugs and mice! Quiver, skitter, hop, but whatever you do, don’t shove the toy in your cat’s face. No self-respecting mouse would do that. Also, don’t feel the need to wildly wave the toy around constantly. This might work for kittens, but older cats need more calculated play…bringing me to my next tip:

Take advantage of your cat’s stalk and rush hunting style. Stalk and rush means that the predator spends a lot of time carefully watching prey before making a very hasty and deadly attack. Cats really like the “pre-pounce” phase – where the toy is barely moving for many seconds. Watch their eyes – are their pupils dilated? Is their butt wiggling? Are their whiskers forward? If yes, you have feline focus!

This short burst style of hunting means that you don’t always need 20 minute play sessions with your cat. Several 5-10 minute sessions are likely just as effective! Just make sure your cat has a little time to calm down from the play before taking the toy away.

Use all of their senses! We are visual, so we tend to think that cats are too. But they want to use their senses of smell, sound and touch too! Try toys scented with catnip, or small amounts of mint, valerian or even cat food. Remember their sense of smell is much stronger than ours, so a little bit will go far. The scent may help them track toys as you move them around.

Move toys against a scratchy surface, like under a paper bag or rug, or hide the toy behind a table leg and gently tap the toy against the leg. The sound will immediately pique your cat’s interest!

Be sure to let the cat catch and touch the toy frequently. They have many sensitive nerve endings and whiskers in their face and paws to help them hunt. These are designed to help them capture prey. This why lazer pointer play can get frustrating; they can never catch the toy.

Rotate toysa previous study suggested that cats don’t get bored of play – they get bored of the same old toy. So be sure to take some toys away, and put out different ones. Have multiple interactive toys for play sessions. Switch toys if your cat seems to lose interest and see if she is re-engaged!

 

I hope now you feel a little more inclined to pick up that dusty cat dancer that’s been sitting in the back of your closet and give your kitty a little exercise! You may even have fun and create a bonding moment with your cat…and if you’re lucky, you’ll prevent some behavior problems too!

I thought for my last blog post in 2013, I’d keep things fun! Some people like to make New Year’s Resolutions (I’m not really one of them!), so I thought I’d give those of you who share your home with a cat a few easy suggestions to help increase your cat’s happiness, and enhance your relationship with your feline friend.

1.    Play with your cat with interactive toys DAILY

Interactive play (and I don’t mean throwing a mouse across the room) provides exercise and mental stimulation for your cat, and is a great way to bond (especially if your cat isn’t particularly cuddly).

"I got this."
"I got this."
"I really got this."
"I really got this."
