An animal litter box includes a litter tray for retaining a nonabsorbent litter that includes liquid permeable bottom means, preferably the bottom means defining a plurality of openings sized to allow the flow of liquid waste, but not the passage of litter. The litter tr ay fits into and is supported by a drain pare, the drain pan including an upstanding perimeter wall and a downwardly and inwardly sloping floor that includes a drain hole for the passage o~ liquid waste that has flowed through the litter tray liquid permeable bottom means. The liquid waste flows into and is collected by a reservoir drawer that is removably positioned within a base so that the liquid is captured by the reservoir drawer as it bows down the drain pan flo or and through the drain pan hole. The base includes an upstanding perimeter support wall that has an opening for the placement and removal of the reservoir drawer, and the base supports the drain pan within its perimeter wall. Alternatively, the drain pan and base are formed into a different base by the combination of the drain pan arid the first base into an integral single uni t, rather than a two piece combination.
