The basic apparatus includes an abrasive layer and a grid. The grid is installed over the abrasive layer, a shorter distance from it along one of its edges and a greater distance from it at the opposite edge. The shorter distance is about 1/8 inch and the longer distance 3/8 of an inch. One quarter inch hardware cloth is an acceptable grid material. Preferably the apparatus is mounted on a generally vertical surface near a litter box, such as on the inside of a wall of a covered litter box. The abrasive surface may be replaceable and faces the grid and cats use the abrasive surface and grid simultaneously.
