The Sphynx is a breed of cat known for its lack of a coat. The contemporary breed of Sphynx is known also as the Canadian Sphynx, which is distinct from the Russian Sphynx breeds like Peterbald and Don Sphynx. Lack of coat makes the cat quite warm to the touch. Whiskers and eyebrows may be present, either whole or broken, or may be totally absent. The skin is the color their fur would be, and all the usual cat marking patterns (solid, point, van, tabby, tortie, etc.) may be found on Sphynx skin. Sphynxes generally have wedge-shaped heads and sturdy, heavy bodies. Standards call for a full round abdomen, also known as pot bellies. Sphynxes are known for their extroverted behavior. They display a high level of energy, intelligence, curiosity, and affection for their owners. Sphynx cats lack a coat to shed or groom, they are not maintenance free. Body oils, which would normally be absorbed by the hair, tend to build up on the skin.
