ABSTRACT:
This invention is a simple, easy to use, self-cleaning pet litter box that separates reusable litter material from solid pet droppings. This task is accomplished through the use of swelled-out chutes strategically formed along the litter box walls combined with a trough-shaped, wire mesh separator that is also built into the litter box. A hole is cut in the side wall adjacent to the wire separator with a tubular-shaped protrusion extending from the outside of this hole in the wall. By using a tilting, rotating motion, the used litter is passed through the chutes in the walls and into the wire mesh separator. The solid pet waste is trapped in the separator while the still usable litter is filtered through. With one final tilt, the solid waste is dumped through the hole in the wall, through the tubular protrusion, and into an attached disposable plastic bag. This bag connects to the tubular protrusion in such a manner that the bag seals-off and prevents the escape of unpleasant odors, thus allowing several litter cleaning cycles between bag changes.
