Abstract
A wire cage operable between an expanded position and a folded position includes a top wall and a bottom wall, a first sidewall, a second sidewall, a front wall and a rear wall attach to the bottom and top walls. The front and rear walls contain rounded sides. The cage includes an entrance door. A pass through door is mounted on the entrance door. In order to open the pass through door, the entrance door must be closed and locked. The cage top wall optionally contains a top wall door hinged on the edge of the top wall so that the user can easily access the cage from the top wall. The top door can be rotated so that it rests flush with the cage sidewall. A pan is inserted over the bottom surface.
