Abstract
A cage assembly for animals includes a cage having an open-top transparent body and a containment member for the cage body to confine the animals. A filter cap for biologically isolating the encaged animals from the environment surrounding the cage assembly is disposed on the cage. The filter cap has a substantially rigid transparent housing that rests on and encompasses the cage. A portion of the filter cap overhangs a portion of the cage to prevent the filter cap from being dislodged from the cage. An air filter is detachably secured to a roof portion of the filter cap and is protected from damage by a perforated metal plate. All elements of the filter cap are autoclavable and reusable.
