Cage for laboratory animal
First Claim
1. In an animal cage for laboratory purposes, the improvement wherein the cage has a floor means provided with a plurality of perforations formed therein, the perforations being interspersed with a plurality of upwardly-projecting convex projections to assure that the solid and liquid waste from the animal will substantially fall through the perforations in the floor means and will not substantially cling to the floor means adjacent to the perforations, and a removable waste tray disposed below the floor to receive the animal waste.

Abstract
A cage system for laboratory animal care has a plastic cage with a molded perforated-bottom, a snap-on plenum cage top, a cage top feeder lid and a snap on waste tray. The floor of the cage is shaped with rounded perforations and domed protrusions to deflect both liquid and solid waste down to the attached waste tray. A filtered air supply is introduced into the lid of the cage and passes through orifices in the bottom of the lid, flowing laminarly through the body of the cage and out perforations in the floor over the waste tray. A water supply system for the cage is provided. No bedding is required in the cage. The system is air tight and air in any one cage is isolated from air in all other cages in the system which can be mounted on a rack. A drain for liquids is provided in the waste tray. In an alternate embodiment, the cage has an imperforate floor. A plurality of cages are supported in a rack. Several configurations to support the cage within the rack are provided.
