A rodent cage including a cage bottom having a plurality of integral side walls, a floor and an open top end. A peripheral lip extends continuously around the top end. A pair of recesses are disposed on the peripheral lip. A feeder assembly has a frame and at least one section descending therefrom. The frame has pair of flanges extending therefrom so that when the feeder assembly is disposed in the cage bottom the pair of flanges are mated with the pair of recesses, respectively. A bonnet is dimensioned in size for sealing the top end of the cage bottom. A lock is disposed on the bonnet for preventing rodents housed in the cage from displacing the bonnet from the cage bottom.

Feeder assembly for use in a cage

Multispecies rodent cage

A wire bar lid for use in an animal cage is provided having a thin perimeter having a substantially rectangular cross-section. A plurality of wires are supported within the perimeter below the plane of the perimeter.

Ventilated cage and open rack system

A waste management disposal system which disposes of both solid and aerosol waste includes a housing divided into a solid waste containment area and a negative pressure plenum for drawing aerosol waste away from the solid waste containment area. A funnel is provided for guiding solid waste into the waste containment area and the negative pressure plenum draws the aerosol waste in a path orthogonal to the funnel. A filter is provided for filtering the aerosol contaminants from the air upon which it is being transported.

Waste management disposal system

A ventilated animal cage rack has a hollow housing divided into a plurality of horizontally-disposed shelf compartments separated from each other by partition walls and having front open ends normally closed off by transparent doors which isolate the interiors of the shelf compartments from each other and from the interior of the room containing the cage rack. Each shelf compartment is sized to contain a row of horizontally-spaced animal cages having open top ends and closed bottom ends, with the open top ends spaced well below the ceiling of the shelf compartment. A low pressure air plenum extends vertically along one side of the cage rack and communicates with one side of each of said shelf compartments, the other sides of which contain air inlet openings communicating with the room interior, thereby providing a low-pressure negative air flow along the top open ends of the contained animal cages to said air plenum and then to a room exhaust system. The animal cage rack is provided with a watering system including an individual water dispensing valve for each of the contained animal cages, and each cage is provided with an access opening through which the animals therein may reach the respective dispensing valve. Each shelf is provided with a guide member for each animal cage stored therein, each guide member being precision formed to insure accurate registry of the access opening of the inserted animal cage with the respective water dispensing valve.
