ABSTRACT:
Transparent panels form a plurality of enclosures which have inlet and exhaust ventilation openings. The input ventilation openings are coupled to a plenum chamber and the exhaust ventilation openings are coupled to an exhaust chamber. Air flow is maintained from the plenum chamber through the enclosures and out the exhaust chamber by a pressure differential between the plenum chamber and the exhaust chamber. This is accomplished by maintaining the plenum chamber at a positive pressure with respect to the enclosures and maintaining the exhaust chamber at a negative pressure with respect to the enclosures. Air is not recirculated through the cages, and both the input and the exhaust air is sterilized by various devices in the path of the ventilation stream. Cleaning of the enclosures is accomplished by flushing any waste material into the pathway coupling the enclosures with the exhaust chamber. The use of the transparent panels enables various murals to be positioned to give the people who are viewing the animals a feeling of being in a more natural environment. Also, because the enclosures are not air tight, music may be played in the public area which can be heard by the animals in the enclosures.
