A cage includes side panels, each having top and bottom edges extending along a length of the cage. Coextensive top and bottom panels have sides extending along a length of the cage and are engaged with the side panels, defining a cavity therebetween. End panels are conjoined to the top, bottom and side panels. One end panel includes an access door pivotal about a fulcrum axis. Each side, top, bottom and end panel is formed from rigid steel shafts arranged in a mesh pattern. A mechanism is included for locking the access door at a lowered position. Spikes extend from the cage for deterring animals from tampering therewith. The spikes fit between the mesh pattern and lay coplanar with the side, top, bottom, and end panels during lowered positions. The spikes are evenly spaced along the panels. A mechanism is included for rotating the spikes between extended and retracted positions.
