A pet litter device includes: a base configured to be placed on a support surface, the base defining a recessed portion that comprises a recess surface defining an opening, and a drum rotatably connected to the base and partly received in the recessed portion. The drum has an outer lateral surface. The recess surface and a portion of the outer lateral surface that faces the recess surface define a gap and form a passage in communication with the opening. The recess surface is to guide litter particles entering the passage to pass through the opening to fall on the support surface.
