ABSTRACT:
A cage well suited for confining and rearing mice, rats and like relatively small animals in a germ free, hygienic atmosphere for experimentation purposes. Included is a boxlike casing with its open top closed by a horizontal lid. There are provided an air supply conduit for supplying germ free air into the casing, and an exhaust conduit for drawing air from within the casing, both extending into the casing through a side wall of the casing. The air supply conduit extends in parallel relation to the inner or lower surface of the lid and is formed with a series of air supply holes directed upwardly, so that supplied air flows upwardly against the lower surface of the lid and is then turned downwardly, whereby the supplied air does not impinge directly upon the animals, thus providing conditions favorable for the rearing of the animals.
