Not a veterinarian, not medical advice. Petacent publishes buying guides. We do not diagnose, prescribe, or endorse treatments. Diet changes, pain, litter-box avoidance, and sudden behavior shifts belong with a licensed veterinarian who has examined your animal.
Litter-Robot 4 is the automatic box we put first in best automatic litter boxes. The job is odor and labor, not diagnosing UTI from an app graph.
You still buy litter that clumps the way Whisker wants. You still wash parts. “Never scoop again” is marketing for “scoop the drawer on a cadence.”

- Best for
- One- to four-cat homes that will pay flagship money to empty a sealed drawer instead of scooping daily.
- Skip if
- The cat is under the published weight guidance, $699 is the whole pet budget, or scooping is not actually the leak.
- Pricing note
- Public retail commonly $699 for the standard unit. Bundles cost more. Optional Whisker+ is extras. As of September 20, 2026.
