Unquestionably the least handsome of cats, the Sphinx was preserved originally as a novelty, having appeared as a mutant. It is now frequently exhibited in shows, always commanding attention and comment. Kittens are born with a light covering of normal-length hair, but this disappears before they are weaned. The adult's body is covered with very short, dense hair that has the feeling of suede. In many places the skin shows through. The Sphinx has no whiskers. Its eyes are gold, and its tail is long and whiplike.

Because it lacks the protective coat of the normal cat, the Sphinx prefers warm weather, or it must be kept indoors and away from drafts to prevent it from catching cold. The cat, like the duckling, is oblivious to its ugliness and seems to be more sociable and affectionate than many other breeds.
