My cat eats too fast. Not "a little eager." Full scarf-and-barf. She inhales her food, waits roughly four minutes, and then deposits the entire meal, undigested, onto my rug. The vet said it is common in cats fed from a flat bowl, and the fix is simple in theory: make the food harder to get at. In practice, that sent me down a rabbit hole of slow feeders.
The PetSafe SlimCat is the one I bought first, and the one I still use on days when I want her meal to last longer than a commercial break.
What it actually is
A hard plastic ball, about the size of a tennis ball, with a screw-off lid and two adjustable openings on the sides. You fill it with kibble, snap it shut, and put it on the floor. The cat bats it around, kibble falls out a few pieces at a time, and dinner takes twenty minutes instead of ninety seconds.
It is not complicated. That is the whole point. There is no app, no battery, no assembly. It is a ball with a hole in it, and that is exactly enough.
The adjustable opening is the real feature
Most cheap food balls have a fixed hole size. That sounds fine until you realize kibble comes in wildly different sizes. A ball built for small dental kibble will not dispense the chunky urinary-health kibble my cat eats — it just rolls around with the food trapped inside, and the cat gives up.
The SlimCat has a rotating ring on each opening that lets you change the gap from "barely open" to "wide." I spent ten minutes finding the slot that dispenses her exact kibble at a rate of about one piece per bat. Once set, it stayed set. I have not touched it in two months.
What actually changed at mealtime
Before the SlimCat, my cat finished her meal in about 90 seconds and threw up roughly one in three meals. After — once she learned to bat the ball, which took two meals — her meals last between 15 and 25 minutes, and the throwing up stopped entirely. Not reduced. Stopped.
The vet's explanation: the vomiting was from eating too fast and swallowing air, not from the food itself. Slow the eating down and the air-swallowing drops, and the carpet stays clean. That is exactly what happened.
A bonus I did not expect: she gets more exercise. A cat batting a ball around the living room for 20 minutes is doing something close to a hunt. She sleeps harder after a SlimCat meal than after a bowl meal.
The ball that ended the scarf-and-barf
The PetSafe SlimCat is the simplest fix I found for a fast-eating cat. Adjustable openings mean it works with any kibble size, and my cat's mealtime vomiting stopped completely once she stopped inhaling her food.
See the PetSafe SlimCat on Amazon →What annoyed me
I want to be honest, because the reviews that pretend everything is perfect are useless.
First: it is loud on hard floors. Plastic ball rolling on hardwood at 6am sounds exactly like you think it does. I put down a rug in the feeding spot and it got much quieter, but if you have all-hardwood floors and a light sleeper, this will be a thing.
Second: a determined cat can crack the lid open. Mine has not, but a friend's large male cat popped it once and ate the whole refill in 30 seconds. If your cat is a brute, check the lid is snapped fully shut every time you fill it.
Third: it holds about a quarter cup of kibble comfortably. If your cat eats a full cup at a meal, you will be refilling it mid-meal, which defeats the "set it and walk away" appeal. For my cat's quarter-cup meals it is perfect.
How I introduced it
Do not fill it and hand it to a cat who has never seen one. Put a small amount of kibble in, set the opening wide, and roll it past her a few times so kibble falls out near her. She connects "ball moves, food appears" within one session.
Once she is chasing it, narrow the opening a little each meal until the meal lasts 15 to 20 minutes. Too narrow and she gets frustrated and walks off; too wide and it is no slower than a bowl. The 15-to-20-minute range is the sweet spot the vet mentioned.
If your cat is a flat puzzle-feeder cat — she already uses something like the Cat Amazing Mega — the SlimCat is a good outdoor or floor complement, not a replacement. They serve different moods.
Who it is not for
If your cat is elderly and does not move much, a rolling ball is asking her to exercise when she cannot. A stationary lick mat or a flat puzzle box is kinder.
If your cat is on a strictly wet-food diet, this will not work — it is a dry-kibble device. Wet food needs a lick mat, not a rolling ball.
If you have a dog, keep the SlimCat away from him. A medium dog will destroy a cat-sized plastic ball in about ten seconds. This is a cat-only item.
The bottom line
The PetSafe SlimCat is the least fancy thing in my cat's enrichment rotation, and it is the one that solved a real medical-adjacent problem. The scarf-and-barf cycle is gone. Meals last twenty minutes. She sleeps harder. For a fast-eating cat on dry food, this is the first thing I would tell a friend to try.
