ABSTRACT:
A prism shaped in the form of a truncated obround, has one end defining an aperture through which a cat can enter. Internally, the hedron defines a plenum but transcending through a sector of the hedron, the plenum is sub-divided into a first and second sub-plenum by a sieve preferably in the shape of a plurality of spatially disposed parallel slats extending from front to rear. On the upper margin of the sieve is a collection station adapted to collect solid and urine saturated waste from a cat. The interior of the hedron is partially filled with granular cat litter and on defecation of a cat, the solid and urine saturated waste are consumed, in part, by the cat litter. On rotation in one direction and counter-rotation in the other direction, the cat litter is passed through the sieve into the second sub-plenum while at the same time, the solid waste and urine saturated waste pass over the screen into a collection station where they are collected on the moment of counter-rotation which step also causes the clean cat litter in the second sub-plenum to flow back into the first sub-plenum which is in communication with the aperture.
