Abstract
A cat litter box of the pass through type which includes a tray on which the litter is deposited with the tray having openings in the base for the passage of liquid wastes into a sump or other means for the collection of liquid waste separate from the litter, a convenient means for releasing the collected liquid and means for reducing the release of odors from the collected liquids and residues which cling to the litter. The box is used with litter of a granular type that sheds liquids, and mitigates odor from residues and liquids which have been shed.
