Origin & colors
The Sphynx is not the first instance of hairlessness in domestic cats. This natural, spontaneous mutation has been seen in various locations around the world for more than a century, and probably much longer.
The Sphynx comes in all colors and patterns, including white, black, red, chocolate, lavender, various tabby patterns, tortoiseshell, calico, bicolor, and pointed and mink patterns. The color is seen in the pigment of the skin as well as in whatever hair the cat has and can sometimes be difficult to distinguish.
Size
The most distinctive feature of this cat is its appearance of hairlessness. The Sphynx is of medium size and body conformation with surprising weight for its size. The body feels warm and soft to the touch, with a skin texture akin to either a soft peach or a smooth nectarine. The Sphynx is sweet-tempered, lively, and amenable to handling.
Personality
To say Sphynxes are lively is an understatement; they perform monkey-like aerialist feats from the top of doorways and bookshelves. Very devoted and loyal, they follow their humans around, wagging their tails doggy fashion, kneading with their padded toes, and purring with delight at the joy of being near their beloved humans. They demand your unconditional attention and are as mischievous (and lovable) as children. And despite all that and their alien appearance, they are still entirely cats, with all the mystery and charm that has fascinated humankind for thousands of years. While the Sphynx may not be for everyone, its unique appearance and charming temperament has won it an active, enthusiastic following.
Care
Although 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. As a result, regular bathing is usually necessary weekly or bi-weekly.
