Siamese Cat

The Siamese cat is one of the first distinctly recognised breeds of Oriental cat. The origins of Siamese cat are unknown, but it is believed to be from South-East Asia, and are said to be descended from the sacred temple cats of Siam.
 All Siamese cats have a creamy base coat with coloured "points" on their muzzles, ears, paws and lower legs, tails and scrotums in males. The dark coloration on the "points" of the coat is produced by an enzyme that isheat-sensitive; it fails to work at normal body temperatures, but becomes active in cooler areas of the skin.
 All Siamese cat, although pure cream or white at birth, develop visible points in the first few months of life in colder parts of their body. By the time the kitten is four weeks old the points should be clearly distinguishable enough to recognise which colour they will be. Siamese cats tend to darken with age, and generally adult Siamese living in warm climates have lighter coats than those in cool climates.
Siamese have almond-shaped, bright blue eyes and short, flat-lying coats. Many Siamese cats from Siam had a kink in their tails but over the years this traits has been considered to be a flaw and breeders have largely eradicated it. Many of the early Siamese were cross-eyed to compensate for the abnormal uncrossed wiring of the optic chiasm, which is produced by the same albino allele that produces coloured points. Like the kinked tails, the crossed eyes have been seen as a fault and through selective breeding, the trait is far less common today.

Original siamese cat

The original Siamese cat imports were medium-sized, rather long-bodied, muscular, graceful cats with moderately wedge-shaped heads and ears that were comparatively large but in proportion to the size of the head. The cats ranged from rather substantial to rather slender but were not extreme in either way.

The Siamese voice, which they use frequently, is unlike that of other breeds, and has been compared to the cries of a human baby. As they are "wired for sound", they can meow loud enough to compete with fire and rescue equipment. The Siamese temperament is legendary: like all Oriental cats Siamese are active, playful, extremely vocal and persistent in demanding attention. They usually get on well with other cats, especially other Siamese cat or related breeds, but they also have a great need for human companionship and often will engage in crazy antics to get the attention of their people. Siamese cats are generally believed to be highly intelligent (by cat standards), and their behaviour usually reflects this. Siamese are often described as "dog-like" because of their loyalty, often attaching themselves to one human in a household, and their trainability--they can be taught to walk on a leash, fetch and perform tricks.
