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.

A disposable cat litter box, comprising: a. a rectangular base having opposing side edges and end edges; b. a pair of opposing sides extending upwards from said side edges of said rectangular base; a pair of opposing ends extending upwards from said end edges of said rectangular base; said sides and ends being joined to form a box; each side and end having a top edge; c. a pair of opposing side extensions continuing from said top edges of said sides, which, when the box is in a closed position, are folded at said top edges of said sides so as to form a top to said closed box; and, when the box is in an open position, extend upwardly to an approximate transverse midline, whereat each side extension is folded approximately 180-degrees inward and downward; d. a pair of opposing end extensions continuing from said top edges of said ends, each end extension having opposing side edges from which a pair of flaps extend; said opposing end extensions, when the box is in a closed position, folding inwardly at said top edges of said ends so as to lie beneath the top of the closed box; and, when the box is in an open position, extending upwardly with the flaps extending orthogonally inward; e. said opposing end extensions additionally having a tab formed therein proximate each of the opposing side edges of the end extensions; said tabs being formed within said end extensions so as to rotate inward; wherein, when the box is in a closed position, said tabs remain flush with the end extensions; and, when the box is in an open position, with the side extensions extending upwardly from the sides, the end extensions extending upwardly from the ends with said flaps extending inwardly, and the side extensions being folded approximately 180-degrees over said flaps so as to embrace said flaps therein, said tabs, when rotated inward, resiliently engage and restrain said folded side extensions from unfolding; f. said folded side extensions enclosing said end extension flaps to maintain said end extensions in an upright position and said side extensions being held in an upright folded position by said end extension flaps and said inwardly rotated tabs, so as to form a disposable cat litter box with a sturdy extended wall about its perimeter.
