Abstract: A body defining a cavity, a model of a female reproductive organ held in the cavity, and a model of a sheet of skin that covers the body cavity. The reproductive-organ model includes a Y-shaped element with all three legs detachably coupled to the body. And the skin model is at least partially detachable from the body. In one aspect, the skin model includes a liner mounted adjacent the inner surface of the skin and adapted for realistic grasping, tenting, incising, and suturing of the liner. In other aspects, the skin model includes two layers of contrasting colors for ease of distinguishing them and/or is made of a material mimicking the feel and response of the abdominal skin of an actual animal when suturing the skin. In other aspects, the reproductive-organ model is excluded for use in only practicing suturing and/or tying ligature bands but not spaying.
