ABSTRACT:
A pasteboard cat litter structure comprising a shallow, rectangular, plastic-lined, box-like base adapted for holding a quantity of cat litter. Attached to the top of the base is a collapsible enclosure shaped like a house. The enclosure comprises first and second opposite end panels which fold downwardly and inwardly along a lower crease line to lie flat atop the base when the enclosure is collapsed. The enclosure further comprises a continuous, central portion made up of first and second side panels and an enclosure roof. The central portion is constructed having two (2) opposing, longitudinal, side creases and a roof crest crease, which permit the central portion to be folded down, bellows-style, on top of the folded-down end panels. A flat, substantially closed structure, about the height of the base is then formed. A lid, similar in shape to the base is provided for covering the folded-down enclosure and base, the base fitting downwardly into the lid when the enclosure is erected. A partial cut-out in one side panel hinges outwardly or inwardly about a vertical crease to form an entrance into the enclosure when the enclosure is erected. The cat litter structure can be re-used or the enclosure can be collapsed and the lid installed so the entire structure can be disposed of with used litter inside.
