Abstract
A small animal breeding apparatus has a frame structure in which a number of breeding spaces are defined. Each breeding space is provided with a pair of parallel guide rails fixed to the opposite inner sides of the breeding space and extending from the front side to the rear side. A breeding box provided in each breeding space has on opposite outer sides protrusions which are supported on the guide rails, respectively, for guided sliding movement. A breeding cage having an upper opening is placed on the bottom floor of the breeding box. An air supply pipe and an air exhaust pipe extend forward from the rear of the frame structure. When the breeding box is pushed rearward into the breeding space in guided movement along the guide rails, the air supply and exhaust pipes are caused to extend into the breeding box through insertion holes formed in a rear wall of the breeding box. In this state, the air supply and exhaust pipes are located immediately above the breeding cage, and fresh air supplied through the air supply pipe is caused to flow downward into the breeding cage. The fresh air is circulated in the breeding cage and sucked into the air exhaust pipe, so that air in the breeding cage is maintained clean.
