ABSTRACT:
An adjustable length shelf for a small animal cage having opposite wall members comprises first and second shelf portions which are fitted together in an expansible and contractible telescoping relationship to fit between the opposite wall members of virtually any commonly used veterinary or laboratory animal cage. An adjustment mechanism for forcing the first and second shelf portions apart includes one part mounted on the first shelf portion and a second and coordinating part mounted on the second shelf portion for urging the opposite free ends of the shelf into contact with the cage walls. Opposite end plates are pivotally mounted to the free ends of the shelf for facing engagement with the cage wall members.
