A litter box assembly for pets includes two identical, stackable litter boxes each having a bottom with a pattern of openings and pointed, raised projections. A track extends around the bottom of each box to hold a plate with defines mating apertures and slides back and forth in the track to, respectively, align the openings and close off the openings. A handle on each box attaches to the plate and may be moved to the open position to allow unclumped litter to flow into the box stacked below. The clumped waste is held off the bottom of the box on the raised projections for disposal by dumping. The lower box containing the filtered litter is moved to the top position of the stack to be ready for use.
