A ventilated animal habitat in the form of a frame having at least one
shelf supporting an animal enclosure with a ventilation control region
including an ambient air inlet and exhaust air outlet and a ducting
system also supported by the frame with an exhaust air collection chamber
having a mouth abutting the enclosure around the exhaust air outlet to
capture exiting habitat air drawn under negative pressure by a remote
vacuum source and direct the captured air through a carry way duct while
fresh ambient air is introduced into the enclosure.
