Abstract: A collapsible container having three generally rectangular panels each of which has opposed parallel side edges and opposed parallel end edges. The side edges of each panel are hingedly secured to one side edge of each of the other panels. Additionally, one of the panels includes a fold line extending midway between and parallel to the side edges of that panel thus dividing that panel into two subpanels. The panels are movable between an open and a closed position. In their open position, the panels form a triangular shaped structure whereas in their collapsed position, the panels and subpanels lie in closely adjacent and generally parallel planes to each other. Optionally, the triangular structure can contain cat litter on its interior.
