Abstract: A disposable cat litter holding device such as a box or the like including a horizontally extending bottom preferably rectangular and attached along the ends thereof to upwardly extending end walls and attached at the sides thereof to upwardly extending side walls. An upper side member is secured to each side wall and extends inwardly therefrom horizontally over and parallel to the bottom. Similarly, upper end members extend horizontally inwardly from the upper edge of the end walls horizontally extending over the bottom. Flap means are secured to the sides of the side walls and are adapted to interlock with one another preferably by an interlocking tab and slot device. The end flaps are adapted to be interlocked inside of the end walls such that when the end walls are folded upwardly and the upper ends are folded inwardly a downward bias will be exerted on the interlocked end flaps to cause them to be secured in position and retain the overall structure of the disposable cat litter holding device.
