ABSTRACT:
An apparatus for testing small animal litter in which a plurality of compartments are employed for living quarters for the small animals, such as cats, and for a container with litter to be tested, and these animal compartments are connected by conduits to a compartment for a tester to use to sniff the odor from any one of the animal compartments. Valves are preferably provided in the conduits, and controls for the valves extend externally of the apparatus so the valves can be operated separately by an operator without interfering with individual tests. Fans in or near the top of the compartments are used to circulate air through the animal compartments while the animals are living normally therein, and a fan is provided in the tester's compartment for drawing the air from any selected one of the animal compartments into and through the tester's compartment. Drains are preferably provided in the bottom of the compartments to permit water and other liquids to drain therefrom and to facilitate cleaning of the compartments. The compartments have doors and are preferably sufficiently large that a normal adult can stand erect therein.
