A $899 AI Litter Box Couldn't Tell Two Very Different Cats Apart

Key points

• The Litter-Robot 5 Pro costs $899 and adds AI health features on top of an $8-a-month subscription, making it the priciest model Whisker sells.
• Its Cat ID facial recognition, software that identifies which cat used the box and logs their health data separately, could not reliably tell two visually distinct cats apart after six months of use.
• The WasteID sensor, which is supposed to detect whether a cat left liquid or solid waste, repeatedly misidentified deposits during testing.
• A cheaper sibling, the Litter-Robot Evo at $599, lacks litter-level monitoring, supports fewer cats, and has a drawer that does not always close properly.
• Whisker says the system is designed to learn over time, but the reviewer saw no meaningful improvement across six months.

Robotic litter boxes are genuinely useful gadgets. A motorised globe spins after your cat leaves, filters the clumps into a sealed bin below, and means you only need to empty a drawer once a week instead of scooping every day. For cat owners who travel, or who simply hate the chore, that alone is worth paying for.

The Litter-Robot 5 Pro, made by the Michigan-based company Whisker, wants to go further. At $899, it promises two onboard cameras and a gas sensor that can, in theory, track each cat's weight, bathroom frequency, and even the type of waste they leave behind. The idea is that a sudden change in habits could flag a health problem before symptoms appear. For owners of ageing cats, that pitch is compelling.

The Verge covered the launch last year. After six months of hands-on testing, the verdict is harsher than the marketing suggested.

Does the AI health tracking actually work?

Not reliably, no. The core problem is Cat ID, Whisker's name for the facial recognition feature that is supposed to identify which cat entered the box and log the visit under the right profile.

The tester owns two cats who look nothing alike: a large grey-and-white tabby named Smokey, weighing 13.4 pounds, and a small black-and-white tuxedo cat named Boone. The 5 Pro still confused them. After several weeks, it had merged their profiles, recording both cats at the same weight. Smokey appeared to lose two pounds overnight because the machine had credited his visit to Boone.

False weight data is not a minor nuisance. A vet noticing a two-pound drop in a middle-aged cat would rightly want to investigate. A robot inventing that drop is worse than no data at all.

Correcting the errors, resetting weights, reassigning visits, and fixing video logs, took significant time every week. The camera still did not correctly identify either cat by the end of the test.

Whisker sells a $29 RFID tag, a small chip worn on a collar, to help the system with look-alike cats. That is a reasonable workaround. But a machine advertising facial recognition as a headline feature should not require a separate purchase to function when the cats involved look obviously different.

The WasteID gas sensor, which is meant to detect solid waste faster so the globe spins sooner and contains odour, also misfired repeatedly. Whisker acknowledged the reviewer's gas sensor unit was faulty.

What about the cameras?

The front-facing camera records visits. The interior cameras, the ones that would show you what your cat actually left behind, offer only a live view and do not record. Whisker says recording from interior cameras is coming in a future update.

One practical warning: the front-facing camera records anyone who walks past, not just cats. The reviewer realised after a week that the camera was also capturing family members using a nearby bathroom. An option exists to record only when a cat is detected, but cats do follow their owners into bathrooms, so the setting is imperfect.

Model	Price	Cats supported	Key limitation
Litter-Robot Evo	$599	1 to 2, under 19 lbs	No litter-level monitoring, finicky drawer
Litter-Robot 4	$699	Up to 3	Confusing LED indicators
Litter-Robot 5	Not stated	Up to 5	Mid-tier features
Litter-Robot 5 Pro	$899 + $8/month	Up to 5, up to 30 lbs	AI features underperform

Should you buy one?

The 5 Pro is a good automatic litter box. Its larger globe, clearer LCD screen, and sealed bin make it a better mechanical device than the older Litter-Robot 4. If you want a machine that handles the scooping and nothing more, it does that well.

But the $899 price and the $8 monthly subscription are justified only by the AI health features. Those features did not deliver one actionable insight across six months of testing. Until Whisker fixes Cat ID and the interior camera recording, you are paying a significant premium for software that is not finished.

The $599 Evo is a reasonable alternative for one or two small cats, with the caveat that its build feels less solid and its waste drawer can stick.

Here is the honest takeaway: buy a Litter-Robot for the convenience of automated scooping. Do not buy the 5 Pro expecting a health monitor. Check your cat's actual weight on a plain bathroom scale and note any changes yourself. That costs nothing and is more reliable than what this machine delivered.
