Abstract: A disposable pet litter container characterized by a bottom wall, and side and end walls, where lower portions of the latter are arranged with the bottom wall to define a litter receiving receptacle, and other upper portions are selectively foldable to present either a fully assembled unit or to serve in a covering relationship for the receptacle. The upper portions of the side and end walls angle inwardly, where other upper portions of the side walls depend downwardly and inwardly, combining to minimize unwanted litter passage from the container and, at the same time, to achieve assembly. The container is integral, made from foldable material, and with the application of a moisture impervious coating, either before or after assembly, stops any liquid pet waste seepage.
