Summary
WIRED's current top pick thanks to a built-in 1080p AI camera with 210-degree view, multi-cat face recognition, and a self-sealing waste bag that holds up to 17 days of waste. The 43% larger opening vs. its predecessor makes it viable for big cats.
Built specifically for cat owners who need to monitor bathroom habits — push notifications for every visit, weight tracking per cat, UV cleaning, and radar safety sensors that stop the cycle if anyone gets near. Ideal for cats with urinary health issues.
Pros
- Built-in 1080p camera with night vision, 210-degree view, and AI multi-cat face recognition
- Self-sealing waste bag stores up to 17 days of waste for one cat
- 43% larger opening than previous model — works for cats up to 22 lbs
- Dual odor eliminator cartridges plus sealed waste bin for near-zero smell
- Works on both 2.4GHz and 5GHz Wi-Fi networks
- Push notification sent every time cat uses the box — critical for monitoring urinary health
- Radar system stops cleaning cycle immediately if any person or cat approaches
- Four weight sensors detect cats from just 1 pound — works for nearly all cats
- UV light cleaning in addition to mechanical sifting
- 30 decibels — nearly silent operation with night mode
Cons
- App is overcrowded with ads for other Petkit products
- Multi-cat face recognition degrades significantly after free Care+ subscription ends
- Camera is not movable or repositionable
- Proprietary waste bags and refill rings required ($35 for 3)
- Barrel is cramped for large cats (12+ lbs may feel restricted)
- Expensive at $700
- Pouring new litter through the small entry hole is awkward — a jug works better than a box
- No step to help cats enter — relies on cats being able to jump in
Our take
If you want the most tech-forward litter disposal system on the market right now, this beats the Litter-Robot 4 on features — the camera and health monitoring are genuinely useful, not just gimmicks.
If your cat has a history of UTIs or urinary blockages, this is the litter disposal system you want. The real-time push notification for every bathroom visit is a genuine health tool, not a gimmick.
