Abstract
Abstract A cage for laboratory animals, such as dogs, rabbits, and the like includes a frame having a base and a top and a plurality of support members for supporting cage walls which cooperate with the frame to define an enclosure for at least one animal and one of the cage walls is mounted for swinging movement to open the interior for access thereto and to close same to retain the animal therein. The cage has a urine deflector on certain cage walls with portions supporting a cage floor having openings over substantially the entire area thereof to permit animal waste to pass therethrough and into an open-top receptacle supported on the base of the frame and positioned below the cage floor. The urine deflector has a portion serving as a floor portion substantially increasing the useable floor area of the cage, said urine ledge deflector extending from the respective wall with an inclination sufficient to permit liquid animal waste to flow toward and through the cage floor and into the receptacle while serving as a floor portion.
