  • Patent number: 5769026
    Abstract: A cat litter enclosure is provided including a main housing providing an outer box having an entrance at one end enclosing a removable second housing providing an inner box, smaller than the outer box, having an entrance at an end opposite the entrance into the main housing. A path is provided around the inner periphery of the main housing leading from the entrance therein to the entrance in the second housing. A removable cat litter pan is disposed within the second housing. The path may be carpeted and, since a cat must move along the path to enter the second housing where the cat litter pan is, and retrace its path, its paws will be cleaned of litter and other debris when the cat exists the main housing.
