ABSTRACT:
A disposable cat litter box, preferably made of a single sheet of corrugated cardboard treated to prevent leakage of moisture, is formed so that when a closed box is opened for use, the top is unfolded to the vertical on all sides to provide both end extensions and side extensions. The end extensions include end flaps which extend inward from their side edges, and tabs which have a pre-cut periphery except for an uncut side and are located proximate the end flaps. The side extensions fold downwards upon themselves, at pre-formed longitudinal midlines, about the inwardly extending end flaps of the end extensions, the end flaps providing support for the side extensions. With the side extensions tightly folded downwards, the tabs on the end extensions are rotated inward about their uncut side, wherein subsequent release of the side extensions allows the side extensions and inwardly rotated tabs to resiliently engage, preventing further unfolding of the side extensions, and thus restraining the side extensions in an upright position. The end extensions are locked into their upright position by the embrasure of the side extensions about the end flaps of the end extensions. The interconnection of the side and end extensions establishes a continuous rigid wall about the box. For disposal, the tabs are merely rotated to their original flush positions within the end extensions, thus releasing the side extensions and end extensions for refolding to their original horizontal positions as the top of the box.
