What reviewers found
Petlibro Luma
- Cats.com (4.5/5): Easy setup, quick cat acceptance, quiet raking and a sealed drawer; AI analysis needs a subscription and some owners report weight sensor false detections. Source
- Tom's Guide: After several months with two cats, the cats used it more than a Litter-Robot 5 placed beside it, and the app flagged when one cat stopped using the box for a week. Source
