Abstract
In an apparatus for raising experimental animals, a cage for confining animals is placed in a received position within a cage rack. The cage includes a casing and a lid separate from the casing, for closing an open top of the casing. Slide rails are mounted to the cage rack for sliding the casing of the cage in a guiding direction to the received position within the cage rack. Downwardly concave leaf springs are mounted to the cage rack for resiliently depressing the upper surface of the lid of the cage toward the slide rails for positively holding the lid and the casing against movement when the cage is in the received position.
