Abstract
A cat litter box includes a tray on which the litter is deposited with the tray being inset within a base having inwardly converging bottom walls defining a sump for the collection of liquid waste. A valve is carried by the bottom walls and has a control rod extending outwardly through a base skirt to receive a handle. The litter is of a nonabsorbent type having a smooth exterior surface to facilitate cleaning. The base supports the tray both for cleaning when in place on the rim of a toilet bowl and when on a floor surface.
