An animal restraint includes first and second upright plates. A plurality of bars, each having a first end mounted to the first plate and a second end mounted to the second plate, form an enclosure that is dimensioned to closely receive an animal. The plurality of bars further include at least one gate bar having a first end that is slidably mounted to the first plate and a second end that is slidably mounted to the second plate. The gate bar is slidable along a defined path between a closed position, in which the gate bar blocks an opening in the enclosure, and an open position, in which the gate bar is clear of the opening.
