ABSTRACT:
A pet litter box includes a waterproof pan having a closed bottom, diverging walls and an open top bounded by a rim, a rack having a liquid-permeable planar portion and a plurality of hangers including inverted-U bights which extend over the rim of the pan so as to suspend the rack within the pan, substantially above the bottom of the pan. The bights are interconnected by elements wholly outside the pan, whereby rack can be lifted from the pan. Litter is spread on a screen having a frame conforming to the interior contour of the pan above the level of the rack. Liquid waste can percolate through the litter to the bottom of the pan.
