This fully automatic cat litter box revolutionizes the pet care market with its unique feature of eliminating the need for manual cleaning, completely freeing cat owners' hands. It is ingeniously divided into three main modules: the litter storage area, the work area, and the cleaning area. The litter storage area intelligently manages the supply of cat litter, reducing the burden of frequent refills. The work area is where the cat uses the litter box, and the cleaning area automatically sifts, cleans, and dries the litter, ensuring a tidy environment.
