The Siamese Cat
Depending on the source there are additional types of Siamese Cats besides the four standard coat colors which are: Seal Point Siamese, Blue Point Siamese, Chocolate Point Siamese, and Lilac Point Siamese. Many individuals consider these additional beautiful cats as Siamese. These exotic felines, not only have the beauty of the Siamese cats, but also have the colorful personalities, and intelligence of the Siamese. These beauties are known as the "Colorpoint Shorthairs"
Early breeding introduced the Siamese with a cross of the "red gene". This red gene came from crosses between Seal Point Siamese with red tabby shorthairs. The offspring was again breed with a Siamese. This produced the first hybrid crosses and created two additional solid points. These solid point cats were the first to be recognized and are called Cream Point and Red Point. In 1964 the first Colorpoint Shorthairs were recognized as a breed.
As the Colorpoints gained popularity, "Tabby" versions of the Siamese were introduced to this category. These tabby points are called Lynx Points and have their own class as follows:
Lynx Points Siamese
Lilac Lynx Point
Blue Lynx Point
Chocolate Lynx Point
Seal Lynx Point
Cream Lynx Point
Red Lynx Point
The Tortie Points
Sex-link hybridization of the red gene resulted in an interesting phenomenon called the Tortie Points. The word Tortie is short for "Tortoiseshell". You might recognize this name in relation to the "Calico Cat."
Calico cats are only female cats (or rather male calicos are quiet rare). The red gene is sex-linked, which means that the gene is carried on the sex chromosomes, specifically the X- chromosome. Females are XX, and Males are XY. A male cat with only one X chromosome can only carry the gene for black and red but not both. Females are considered mosaics because the XX can produce red and black together.
The Tortie Point has a very striking appearance. The combination of the red gene and the four Siamese colors creates and random mottling or blotching of colors. They often have a symmetrical split of red and/or cream on one side of the face and the Siamese color on the other half. Just like the calico cats, the Tortie Points are all females.
The color descriptions start with the four primary Siamese colors and are:
Lilac Tortie Point
Blue Tortie Point
Chocolate Tortie Point
Seal Tortie Point
When bred to a lynx parent, the last four of the sixteen colors are the lynx versions of the Tortie Points.
They are:
Lilac Tortie Lynx Point
Blue Tortie Lynx Point
Chocolate Tortie Lynx Point
Seal Tortie Lynx Point
