Best Puzzle Feeders and Slow Feeders for Dogs and Cats

A food puzzle is three different products sold under one name, and buying the wrong one of the three is why so many end up unused. A slow feeder bowl solves speed. A dispensing toy solves boredom. A foraging feeder for a cat solves something more specific: an indoor cat's day has no hunt in it, and the bowl removes the only part of the sequence the cat still gets to finish.

In their review of feeding for feline behavioural wellbeing, Mikel Delgado and Leticia Dantas note that cats allowed to set their own schedule eat roughly 8 to 16 small meals a day, that a mouse is worth about 30 kcal, and that only around a third of a cat's hunting attempts end in a kill. A cat, in other words, is built to work for many small portions. Twice-daily bowl feeding is the least natural arrangement it could be given.

Dogs arrive at a puzzle from the opposite direction. The American College of Veterinary Surgeons describes gastric dilatation-volvulus as commonly associated with rapid ingestion of large meals, and lists a single large meal once a day among the risk factors, alongside a deep chest, age and an affected relative. A slow feeder does not prevent bloat and nothing here should be bought as if it did. It does address the one factor on that list an owner controls at every meal.

We cover what a puzzle can and cannot do for behaviour in our guide to whether puzzle feeders work at all.

Pick the job before the puzzle

Speed. For a dog that finishes a bowl in under a minute, the answer is a slow feeder bowl used for every meal.

Occupation. For a dog left alone or one that pesters in the evening, the answer is a dispensing toy that makes a meal take ten or fifteen minutes of pushing.

Foraging. For an indoor cat, the answer is food split into small portions and spread out, so that eating involves finding. Delgado and Dantas divide cat puzzles into two kinds: mobile ones, filled with dry food and batted around to release it, and stationary ones, with wells or tubes the cat fishes food out of. If a cat ignores one kind, try the other before giving up on puzzles.

Difficulty. The review is explicit that difficulty should match the animal's ability and that a first puzzle should need little effort to release food. Start open, start easy, and raise it only when the animal is finishing without hesitation.

Who each one is wrong for

The Slo Bowl is wrong for any animal whose problem is boredom. It changes how fast a meal goes down and does nothing for the hours after.

The Wobbler is wrong for small dogs, for hard-floored flats at night, and for any dog that has ever destroyed a hard plastic toy.

The Tornado is wrong unsupervised, wrong as a meal feeder, and wrong for a beginner with the covers on.

The Hunting Feeder is wrong for wet-fed cats and for anyone who will not refill it daily. The Food Tree is wrong for small spaces and for cats that already scatter food for fun.

Every item here is wrong as a weight-loss tool on its own, because a puzzle changes the speed at which calories arrive and leaves the total alone. The number that matters is the portion, and the arithmetic behind a dog's feeding chart and the equivalent sum for a cat come before any purchase. Cornell's Riney Canine Health Center makes the point that "heaping" portions quietly add calories, and a scoop of kibble poured into a puzzle is still a scoop.

Setting a puzzle up so it lasts

Use the meal. Measure the day's food and take the puzzle's share out of it. A puzzle stuffed with treats on top of dinner is a weight gain plan.

Feed apart in a multi-animal home. The review cites a survey in which almost half of multi-cat households gave several cats a single food dish, and notes that a cat made to share a feeding station may eat under stress instead of skipping the meal. Puzzles concentrate that problem, because the slow eater is the one that loses out. One puzzle per animal, in separate spaces.

Pair it with play for a cat. A food puzzle covers the end of the hunt. The stalk and pounce at the start still have to come from somewhere, and a short wand session before the meal is the part of the prey sequence a puzzle cannot supply.

Match the material to the mouth. None of the hard plastic puzzles here belongs with a dog that chews them. For a power chewer, stick to firm rubber and apply the same thumbnail test used for chew toys.

Read the peanut butter label. Spreads are a popular way to make a puzzle harder, and the ASPCA lists xylitol, a sweetener in some of them, as a cause of low blood sugar and possible liver damage.

Questions people actually ask

Is a slow feeder or a puzzle toy better for a dog that eats too fast?

A slow feeder bowl. It works at every meal with no learning curve, takes wet food, and the goal is simply a longer meal. A puzzle toy is the better buy for a bored dog, and many households use both.

Will a slow feeder bowl prevent bloat?

No product prevents bloat. The American College of Veterinary Surgeons associates it with rapid ingestion of large meals, and a slow bowl addresses the speed. Breed, chest depth, age and family history are unchanged by any bowl, so a dog at high risk is a conversation for your vet.

Can I put wet food in a cat puzzle feeder?

In the Slo Bowl or a lick mat, yes. In the Hunting Feeder mice or the Food Tree, no, because both are built for dry food. The review of feline feeding notes that puzzles in general can work with wet or dry food, so a wet-fed cat needs a shallow stationary type.

My cat ignores the puzzle. What should I change?

Make it trivially easy. Set the Food Tree to its most open setting, leave a mouse in plain view with kibble falling out, and use it just before a meal when the cat is hungry. If a mobile puzzle still fails, try a stationary one.

How many puzzle feeders does one animal need?

Two or three in rotation. For a cat, several small feeding spots around the home suit the way cats eat better than one hard puzzle in the kitchen.
