A disposable litter enclosure which, in the preferred embodiment, embodies a moisture resistant box containing, in closed form, cat litter and a pre-formed framework for interconnecting the raised side extensions formed from the top of the box. Alternatively, the framework may be attached to the box or otherwise be available. The framework is a continuous, encircling, rim-like member of rectangular shape with a continuous vertical slot formed in its underside, and, where intended to be packaged within the box, is of less dimension than the closed box. The top edges of the side extensions are slipped into the slot of, and thus engage with, the framework to provide a continuous rigid support connecting the tops of the extended sides. The side extensions of the box, where the framework is packaged therein, are tapered to permit joining at the framework without gaps where adjacent side edges of the side extensions meet. The framework may have its inside flange extended as a leading edge so as to intercept the top edges of the side extensions and guide them into the framework. A small perforated push-out area may be provided on the lower portion of a side extension for small kittens, if needed.

A disposable litter enclosure, as for cats, comprising: (a) a box having, when assembled: (1) a horizontal rectangular base; (2) two pairs of opposite vertical sides, each extending upward from an edge of the horizontal rectangular base and joined together as a box, and each vertical side having a horizontal top edge; (3) two pairs of opposite side extensions, each having a top edge, a bottom edge, and two side edges, the bottom edges continuing directly from the horizontal top edges of the vertical sides and extending an equal distance to their top edge; the side extensions foldable inward from the vertical sides to form a horizontal top to the box when said box is closed; and (4) said side extensions tapering, at both side edges, from their bottom edges inwardly to their top edges, so that when the box is open with the side extensions upwardly unfolded and the tapered side edges abutted, the top edges of the two (2) pairs of opposite side extensions will form a horizontal rectangular perimeter of less dimension than, and centered above, the said rectangular base of the box; and (b) a pre-formed, continuous, encircling framework, dimensioned to fit within and be contained by the said box when closed, which framework includes a continuous vertical slot for engagement of the said rectangular perimeter of side extension top edges, the length, width and depth of the slot being dimensioned so that it fits closely over the top edges of the side extensions when in rectangular perimeter form so as to maintain them in said tapered side-edge abutment; said framework comprising an inside downward extending flange, an outside downward extending flange, and a continuous connecting top joining the said inside and outside flanges so as to present a continuous slot of inverted “U”-shaped cross section; said framework providing continuous rigidity and structural integrity between the individual side extensions.
