发明名称 Odor free litter system
摘要 An improved sifting type pet waste receptacle, commonly known as a litter box, for separating both solid and liquid pet waste from clumping type litter material. It includes at least two solid bottomed pans with a vertical wall portion and an open top, plus at least one sifting device having a perforated bottom portion with a vertical wall portion and an open top. The bottom portion of the solid bottomed pans also include a plurality of projections to prevent clogging of the perforations in the sifting device. Also included is a spill rim to help contain litter material which may be thrown out during digging and/or covering by the pet, with a disposal door added to the vertical wall portion to prevent pet waste from being spilled during disposal.
