Abstract: A simple, disposable cat litter box has a flexible plastic pullstring bag and a crushable one piece skeletal frame containing four corner expanded rigid polystyrene plastic brackets and a connecting rim at its top. For average sized boxes, the thin bag can be extended approximately twelve inches above the frame and has a drawstring near its top edge for closure. The bottom of the bag receives cat litter. The bag has an additional reinforcer bag up to the frame sufficient to withstand cat scratches. When the box is in use, the bag is tightly wrapped around the skeletal frame or adhered or attached by standard means. Preferably, there is a single outer fold parallel to the perimeter of the bag in the midpoint of the portion of the bag that extends above the frame, or alternatively top of bag is left inside space of frame until consumer folds it around the frame.
