Why it matters

Leo's Loo Too separates waste after each visit into a sealed 1.5-gallon (6 L) drawer, with bamboo carbon filters and UV odor control. Smarty Pear puts it at about 30 dB.

It's designed for cats from 1 to 20 lb, so most kittens can use it, with radar motion detection, four weight sensors and anti-pinch protection. The app runs cleans, tracks weight and sends alerts, with no subscription fees. It carries a 3-year warranty.

Who it's for, and who should skip it

Good fit if

  • Kittens and adults
  • Quiet rooms
  • Odor-sensitive homes

Look elsewhere if

  • Homes without a level spot near an outlet
  • Cats that are afraid of moving parts
  • Kittens under the maker's minimum weight

Pros and cons

Pros

  • UV odor control
  • Cats from 1 lb
  • 3-year warranty

Cons

  • Clumping clay litter
  • 6 L drawer
  • Large footprint

Limitations to weigh

  • Set it on a hard, level floor near an outlet. Weight sensors read wrong on carpet or uneven tile, which can stop or trigger cycles.
  • Automatic cycling has a minimum cat weight; keep automatic mode off for kittens under it and run cleans manually.
  • Empty the waste bin before it's full and keep spare bags; an overfull bin is the most common cause of a stalled cycle.
  • Running costs come from the bags, liners, filters and litter the maker specifies. The compatibility checker lists refills that state they fit.
