<p>A litter box for a domestic animal such as a cat has a bottom (24), a top (23), opposing side walls (21, 22), and front and rear walls (25, 26). There is an interior divider (35), with an upper imperforate portion which comprises a collection means such as a tray (30), preferably accessible from the exterior of the box, and a lower portion substantially perpendicular to the bottom, having perforations (37). The area of the litter box on one side of the divider is for the cat or other animal to occupy, a suitable entry port (27) being provided through the front wall. If a suitable perforation size is selected for the separation means, clean litter material will pass through the separation means on rotation of the litter box about a horizontal axis parallel to the divider, and wastes and clumped litter material will be separated from the remaining clean litter material. On counter-rotation of the box to its original position, the clean litter material will pass back through the separation means for reuse, and the separated wastes will pass into the collection means, from which they can later be removed. Preferably, the side wall (22) on the side of the divider opposite the side occupied by the animal is semi-circular or at least convex with a smooth curvature to facilitate rotation of the box.</p> |
