ABSTRACT:
A litter box is provided having a litter-holding tray supported over a urine-collection cavity. The litter is contained within a disposable element which generally lines the tray. The disposable element and tray are permeable by liquids so that liquid waste falls from the litter cavity to the lower urine-collection cavity. The disposable element may be lifted and disposed of, along with the litter, in a clean and sanitary manner which avoids touching of the litter. The top, bottom container and tray are stackable and securable together in an easily disassemblable manner. The disposable element is preferably made of a biodegradable material including cornstarch and soy protein or a suitable biodegradable paper.
