Your cat gets a clean box and dinner on time, and you get a bit of your day back. We’ve lined up eight current US models on the specs their makers publish, so you can pick by cat, space and routine.

The eight
Whisker Litter-Robot 4
The Litter-Robot 4 sifts waste from clean litter after each use, so there’s no scooping. You just empty the drawer. The Whisker app shows waste and litter levels and your cat’s weight after each visit, and it’s listed for up to 4 cats, each at least 3 lb. For odor, it takes carbon filters or optional OdorTrap packs.
Suits: multi-cat homes that like keeping an eye on weight.
Worth knowing: when we checked, it was sold on amazon.com by a third-party seller rather than by Whisker, so look at who the seller is and the warranty before you buy.
PETKIT PuraMax 2
The PuraMax 2 has a roomy 76L interior for cats from 3.3 to 22 lb, 7 infrared and 4 weight sensors, a sealed 7L waste bin, and auto, manual, timer and empty modes in the app.
Suits: bigger cats and homes with more than one cat.
Worth knowing: the listing says not to put it on carpet or mats, and it isn’t for kittens under 6 months. It also needs 2.4GHz Wi-Fi.
CATLINK Open-X
The Open-X keeps its entrance open with a 360° view, which may suit cats who are nervous of hooded boxes. Its 12L drawer holds up to 15 days of waste for one cat, it’s listed at 30dB, and the app gives you per-cat reports. A 9-point safety system uses weight, infrared and anti-pinch protection.
Suits: timid cats and quiet homes.
Worth knowing: the 15-day figure is for one cat, so with more cats you’ll be emptying the drawer more often. The listing states a one-year warranty.
PETLIBRO Luma
The Luma adds an AI camera that watches the waste and can tell #1 from #2. It recognizes up to 10 cats, has an open top for cats up to 22 lb, and comes with an 11L sealed bin and a 2-year warranty, per the listing. Visual, weight and infrared sensors pause cleaning when needed.
Suits: owners who want to keep an eye on their cat’s bathroom habits.
Worth knowing: AI analysis and video recordings need a subscription. The livestream is free, per the listing.
PETLIBRO Automatic Pet Feeder (5L, Wi-Fi)
This feeder holds 5L of dry food and serves up to 10 meals a day, 1 to 48 portions each. It works on 2.4GHz and 5GHz Wi-Fi, and you can record a 10-second meal call so your pet knows dinner’s ready.
Suits: cats and dogs on a fixed feeding plan.
Worth knowing: it has no camera, so you can’t see whether the meal got eaten.
PETLIBRO Automatic Pet Feeder with Camera
This one adds a 1080p night-vision camera and two-way audio to a 5L sealed tank and up to 10 meals a day.
Suits: checking in on your pets while you’re out.
Worth knowing: it’s listed for cats and small dogs, so bigger dogs need something else.
PETKIT Automatic Pet Feeder (3L, Wi-Fi)
A 3L feeder with a stainless steel bowl, up to 10 meals a day and battery backup if the power drops. The listing estimates about 15 days of food for an adult cat.
Suits: one cat, or a smaller space.
Worth knowing: 2.4GHz Wi-Fi only.
PETKIT YumShare Dual-Hopper Feeder with Camera
Two hoppers with separate feeding plans, a 1080p camera with a 140° view and night vision, and two-way audio. You can set camera hours and switch off voice recording in the app.
Suits: two pets, or two different foods.
Worth knowing: the listing doesn’t state capacity or meals per day.
How to choose
- Cat size and number. Check the weight range and how many cats each box is listed for.
- Nervous cats. An open design such as the CATLINK Open-X or PETLIBRO Luma may be easier for them to accept.
- Floor. Put litter boxes on a hard, level floor. The PuraMax 2 listing specifically warns against carpet and mats.
- Feeding while you’re away. A camera feeder lets you see that the meal was eaten.
- Wi-Fi. Some models need 2.4GHz, so check your router.
