Best for Health Monitoring

Smarty Pear Leo's Loo Too

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.

$700
Pros
  • 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
  • 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
Why we recommend it

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.

What the experts said

I appreciate the ability to ignore the litter for as long as possible yet still monitor my babies' habits. That's the best of both worlds.

There are four weight sensors inside the barrel to detect when a cat is still inside. It needs just one pound of weight to detect your cat, so that works for all but the littlest of kittens.

Probably the closest competitor to the Litter-Robot is Leo's Loo Too litter box (8/10, WIRED Recommends). I also loved how it looked.
