A litter box accessory wherein a generally concave grate is seated over the base of a tray. The tray is removable and hinged to a litter box to prevent the scattering of cat litter about the home from either an animal kicking or tracking it out of the litter box. The concave grate is made up of a checkerboard pattern of pyramidal protrusions and circular spaces for passage of debris therethrough.
