Abstract

Abstract A sanitary facility for animals, and more particularly a litter box for cats includes a tray having a first portion defining a toilet area and a second portion having a mesh or screen thereover defining an entrance and exit path for the animal. A removable top enclosure portion is provided and a divider partially separates the first and second portions of the box so as to provide a limited passageway therebetween. A doorway is formed in the cover which is offset relative to said passageway so as to provide a tortuous entry and exit path between said door and said toilet area. This forces the animal to walk over the mesh or screen portion so as to prevent litter from being kicked or carried out of the device.
