An improved animal caging system of the type having a plurality of ventilated cages suspended on flanges from a plurality of shelves is provided. The ventilation duct system is entirely enclosed and forms an integral part of the caging system rack. Valves mounted in the air ducts or inlets on the cages, for controlling airflow to and from cages, and an arrangement for a tight fit between the cages and the ducts minimize the possibility of cross-infection between occupants of different cages, and between people and cage occupants. The valves are actuated upon insertion of the cage into the rack, whereby the cages and/or air ducts are sealed upon withdrawal. A negatively pressurized isolation box, adapted to interface with the cage rack, permits manipulation and servicing of cages and occupants, resulting in a contagion-safe total system.

A contagion-safe animal housing system, comprising: a plurality of animal cages of material impervious to air, the cages mounted in a rack, the rack having internal ducting communicating with air supply and exhaust openings for the cages; cage lids sealingly fittable on each of the cages, the lids having air passages corresponding to the air supply and exhaust openings in the rack; airflow controlling means located in the lids, the airflow controlling means operable by contact with the rack to open the air passages in the lids upon mounting the cages and biased to close the air supply and exhaust upon withdrawing the cages; and, means for supplying and exhausting air to and from said ducting in the rack.
