Abstract
An automatic cat litter box includes a rotating drum mechanism. The rotating drum mechanism includes a rotating drum, a door assembly movably connected to the rotating drum, and a waste collection compartment. The door assembly includes a pressing portion. The waste collection compartment is disposed in the rotating drum. The waste collection compartment includes an opening portion. The opening portion is annular. When the door assembly is closed, the pressing portion is engaged with at least a portion of the opening portion. At this time, the pressing portion and the opening portion limit and support each other. The pressing portion limits a deformation of the opening portion, and the opening portion also limits a deformation of the pressing portion, thereby preventing cat litter leakage caused by deformations of the door assembly and the waste collection compartment.
