Abstract

A combination food and liquid dispenser for an animal cage including a first compartment and a second compartment being in vertical relation to each other. The second compartment is constructed to receive food therein and provide an animal access to the food item disposed therein and the first compartment is constructed to receive a liquid container therein and provide an animal with access to the liquid container disposed in the first compartment. A bracket assembly is affixed to the dispenser and supports the dispenser within the cage on less than four side walls thereof. A filter cap for the animal cage includes a body portion dimensioned to fit upon and cover over the top of the cage. Disposed in the interior of the body portion is an air filter, a retainer for retaining the air filter in close proximity to a top wall of said body portion, a protective cover for protecting the integrity of the air filter and the retainer, and a lock for releasably securing the air filter, the retainer and the protective cover within the interior region of the body portion.
