Abstract An animal litter box provided with a mechanism for replacing fouled litter includes a base member supporting a housing for rotation about a transverse axis, the housing including an open topped lower litter box section and an open bottom upper storage box section in end to end engagement with the lower section and releasably locked in such engagement by hasp mechanisms. A plastic garbage bag is housed in the storage section with its opening border clamped between the confronting faces of the upper and lower sections and a pair of opposing flaps supported by opposite faces of the storage box are swingable between a closed position clamping the bag below its peripheral border and an open bag open position, the flaps being releasably magnetically retained in closed position by complementary latch members on the flap member and a hinged door registering with an access opening in a wall of the storage box. The litter box section is also provided with an access opening and a hinged closure door therefor.
