Abstract: A cage has a front, a rear, a first side, a second side, a top, and a bottom panel and at least one door formed through and operatively coupled to one of the panels. The cage further has an integrated handle and lock mechanism coupled to the at least one door. The lock has one or more catches that engage one of a plurality of horizontal bars or a plurality of vertical bars that form the panel containing the door. The integrated handle and the lock is rotatable between (1) a first locked position where the handle is parallel to the door and the catches engage with one of the horizontal or vertical bars that form the panel coupled to the door, and (2) second open position where the handle is no longer parallel to the surface and catches disengage from the horizontal or vertical bar.
