Abstract: An apparatus for use with a litter box is described which is in the form of a tray with a wall along each side and across the front edge to facilitate the containment of excess kitty litter. The walls taper to the floor at the back end of the tray. The back edge, which is blocked off by the litter box during use, is flat to facilitate in the ease of disposal of contained litter and the portion of the tray extending beyond the litter box. The length of the tray may be matched to the size of existing litter boxes available on the market to permit use with an owners current litter control system. The tray easily slides up or back permitting the possibility of an infinite number of tray lengths. The surface of the tray may be textured or ridged to facilitate the removal of the excess litter from the paws of the animals in a contained area as they exit the litter box.
