Abstract: An animal cage rack locking mechanism is provided for releasable locking a cage to an animal cage rack. An indexing arm disposed in a sleeve extends into the slide path of the cage and is coupled to a locking arm also disposed in the sleeve. When the cage is slid into the rack, the indexing arm causes the locking arm to extend from the sleeve to lock the cage in place.

Abstract: An animal feeder that can be mounted on a wall of an animal cage includes a feeder assembly including a back wall, a trough region integrally formed with the back wall and a front wall integrally formed with the trough region and a securing member for securing the feeder asssembly to the wall of the cage. The feeder assembly includes a plurality of slots providing the animal access to a food item placed therein. The animal feeder may include a perch assembly releasably mounted to the feeder assembly. The perch assembly which includes a perch constructed from a plurality of wires, includes a mounting assembly for releasably mounting said perch assembly to said feeder assembly.

Abstract: The ventilated cage and rack system is provided having a plurality of shelves. An exhaust plenum is removably affixed to each shelf for providing air to predetermined air positions along each shelf. At least one cage is provided for housing at least one animal therein, the cage is a cage level barrier having a gas impermeable portion having upstanding sidewalls and a filter positioned on the side wall. A removable cage canopy is mounted to each shelf for guiding the cage toward the predetermined air position and containing air escaping from the filter bonnet within a confined area for removal.

Abstract: 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.

Abstract: A quick disconnect water valve includes a female housing for receiving a male coupling member. The female housing is formed with a channel therein providing a water pathway. An O-ring is disposed within the channel. The O-ring is disposed between a first sleeve and a second sleeve which aligns the O-ring relative to a male coupling member received by the female housing.

Abstract: A ventilated age and rack system having an enclosed ventilated rack and a plurality of barrier cages on the shelves of the rack includes a liquid manifold for transporting a liquid to a plurality of predetermined positions along the shelves. A drinking valve is positioned within the cage to allow an animal to consume liquid supplied by the liquid manifold without leaving the cage. A coupling couples the liquid manifold to the drinking valve so that liquid may flow from the liquid manifold to within the cage when the cage is placed in the rack at the predetermined positions. An air plenum transports positive pressure air to the plurality of predetermined positions. A recessed grommet having holes therein is positioned in the bottom of each cage and allows air to pass from the air plenum to within the cage.

Abstract: The ventilated cage and rack system is provided having a plurality of shelves which act as air plenums for conveying air to a plurality of predetermined air positions within the ventilated rack. At least one cage is provided for housing at least one animal therein, the cage is a cage level barrier having a gas impermeable portion having upstanding sidewalls and a filter bonnet positioned on the sidewall. The plenum shelf removes air disposed at the filter bonnet.
