Litter-Robot is the highest-rated automatic, self-cleaning litter box for cats. Never scoop cat litter again while giving your kitty a clean bed of litter for each use.The Litter-Robot 3 features an expansive litter chamber and larger, upward-facing entryway that gives it an open-air feel, making it much more inviting and comfortable for large cats.

The self-adjusting weight sensor can easily detect both small and larger cats (cats must weigh at least 5 pounds). As with all Litter-Robot units, the litter is automatically sifted after each use and waste is deposited into a convenient drawer, all while using less litter and reducing litter spilling and tracking.
