The Litter-Robot works well with almost any clumping or scoopable litter. Litter beads and crystals that are small enough to pass through the screen will also work.

The Litter-Robot is not compatible with litters that are strictly absorbent, non-clumping, loose clumping, newspaper-based, or wood-based pellets. You’ll find these incompatible litters create a muddy mess and interfere with the sifting process.

Feline Pine is not compatible with the Litter-Robot. The large pellet size does not sift well. It builds up on the screen, causing clean pellets to spill into the waste drawer during the cleaning cycle.

We suggest Cat Evolution Premium Clumping Litter .
