ABSTRACT:
A litter box for pet animals is provided with a ventilating enclosure. When connected to means for exhausting air therefrom, the box and the litter in it are ventilated by flow of air therefrom into the enclosure, from which it is exhausted elsewhere. The enclosure is formed by the floor and sidewalls of the box, a partial cover, and a foraminous barrier between the cover and the floor, preferably formed as a skirt on the cover.
