A cage for housing an animal includes a top wall, bottom, first and second sidewalls, a front wall and a rear wall. A door is disposed in at least one of the walls and is hinged for movement between an open and closed position. The door is mounted in a wall having a doorway. The door includes a plurality of loops on each side of the door. The wall includes a plurality of loops along each side of the doorway. The door loops are positionable adjacent the wall loops when the door is disposed within the doorway to form mating hinge structures. A hinge pin is selectively insertable into either of the door loops on one edge of the door together with the corresponding loops on the wall, to thereby hingedly mount the door to the wall for door swinging movement in either a first direction or a second direction with respect to the wall.
