The present application relates to the technical field of cat
litter box, and particularly relates to a cat
litter box capable of automatically cleaning cat
litter, which comprises a cat
litter box, a bottom plate, a driving motor, a horizontal moving screw rod, a limiting rod, a sliding plate, a screening comb, a multistage hydraulic rod, a rotating seat, a lifting plate, a limiting block, a partition plate and a storage bin, and the bottom plate has an inclined surface; the cat
litter box is square, and the inclined surface of the bottom plate is used for placing cat litter; the driving motor drives the screening comb to move, and carries the cat litter clumps formed by cat
defecation to the top of the bottom plate; when the clumps are carried to the lifting plate, the multistage hydraulic rod is started to push the lifting plate out; when the lifting plate moves above the partition plate, the lifting plate is blocked by the limiting block and is deflected to pour the clumps into the storage bin, thus completing the automatic cleaning of cat litter once; and the problems that the existing cat
litter box is designed in a spherical shape, the volume is too small, the cat litter spreading range is small, and the cat
defecation is easy to adhere to the inner wall of the spherical shape are solved.
