Abstract
Abstract A household pet litter unit for use primarily by domestic cats which not only eliminates undesirable odors, but also eliminates the need to replenish a litter material used by the cat when depositing excreta. The litter unit includes one chemically treated receiving area for liquid excreta, and a second chemical treated area for receipt of solid excreta. The litter material is non-absorbent which is continuously re-usable. The overall design of the litter unit has a sloping feature which directs the pet's use toward one end of the unit.
