ABSTRACT:
The instant invention provides a pet litter box for a household pet such as a cat or a dog. The pet litter box may include a housing having several vertically spaced slots located in one face of the housing and several grooves located on an interior surface of the housing and associated with each slot. The housing may also have a top opening and a bottom opening. A first imperforate tray may be positioned within a bottom slot of the housing and covered with pet litter material. After the pet has used the litter box on several occasions, a perforated tray may be positioned within an upper groove of the housing. Further, a second imperforate tray may be positioned within the litter box above the perforated tray. The litter box may be inverted and shaken, so unused litter material separates from commingled pet waste and used litter material and passes through apertures in the perforated tray. The first imperforate tray is removed from the litter box to expose the commingled pet waste and used litter material, so the waste may be removed from the litter box. The litter box is then ready for reuse, while remaining in the inverted position. A plurality of cleaning elements, such a brushes, may be provided to clean or brush a surface of an imperforate tray during removal from the pet litter box.
