## Verdict

A compact drum box with a good touch screen and an app that weighs cats, but both hands-on reviews found it cramped, hard to deep clean and weak on odor. Consider it only for small cats and at a discount; bigger cats need a roomier box.

- Compact footprint
- Works on 2.4 and 5 GHz Wi-Fi
- App tracks weight and visits
- Touch screen controls on the unit

## Cons

- Cramped inside, large cats do not fit

- App pairing slow and notifications excessive
- Both reviewers found odor control weak
- Reader reports of urine leaks
