A device (10) for receiving and confining an animal, such as a bail, is disclosed.The device (10) comprises a pen (12) having at least two elongate walls (21, 22)spaced apart to define a space into which the animal is received. An entry gateassembly (24) is located at a first end of the pen (12) and is movable between anopen position, which permits entry of said animal into the pen (12), and a closedposition. An exit gate assembly (26) is located at a second end of the pen (12) andmovable between an open position, which permits the release of the animal fromthe pen (12), and a closed position which prevents release of the animal from thereceiving pen (12). At least one of the entry gate assembly (24) and said exit gateassembly (26) includes a pair of door members (30) each having a substantiallyvertically extending planar surface (32). Each door member (30) is rotatablymounted to the pen (12) at the first and/or second end of the pen such that when thegate assembly (24, 26) is moved to the closed position the door members (30) rotatesuch that their planar surfaces (32) abut to extend substantially across thefirst and or second end of the pen (12), and when the gate assembly (24,26) is movedto the open position the door members (30) rotate such that their planar surfaces(32) are located adjacent a respective elongate wall (21, 22) of the pen (12).
