The verdict
Why it scored a 77
The no-touch flagship: waste is heat-sealed into bags automatically so you never handle a drawer, and a rotating 1080p camera tracks stool shape and clump size per cat, which is why Features leads at 95. Against that, proprietary refill rings cost $10-plus per pack, facial recognition was still beta and inaccurate in Cats.com's 3.8/5 test, there is no low-litter warning, and the 32-inch-deep footprint is huge. At $899.99 list ($749.99–799.99 on sale) with an optional PETKIT Care+ plan for full video history, Value is the softest at 62.
