A litter scooper that enables the user to efficiently clean scoopable cat litter from a litter box by removing feces and large clumps of litter soiled with urine as well as the many smaller clumps. Current litter scoopers have a receptacle with only one size of aperture slots to sift the litter that allows the smaller clumps to pass through thus continuing to cause odor in the litter box. The litter scooper of this invention teaches two sizes of aperture slots. The preferred embodiment is a receptacle with rear handle, normal sized aperture slots and a section of the reduced size aperture slots to one side. The invention enables the user to sift out larger clumps of litter saturated with urine and feces by using the section with larger aperture slots and removing the smaller clumps by using the section of reduced size aperture slots. Another preferred embodiment discloses a receptacle with two angular floor sections with the handle on the side between them. The user removes larger clumps of litter saturated with urine and feces by scooping in the direction of the section with larger aperture slots and removes the smaller clumps by scooping in the opposite direction.
