Siamese

The Siamese is a pointed domestic cat breed originating in ancient Siam, modern-day Thailand.

Illustrations of the cat appear in the Tamra Maew, a collection of Thai poems written between the fourteenth and eighteenth centuries. British diplomats imported cats to the United Kingdom in the nineteenth century, and one was sent to the White House in 1878. CFA recognized the Siamese in 1906 as a foundation breed, followed by FIFe recognition in 1949 and championship acceptance in TICA in 1979. Modern breed standards define a long, tubular body with slender bones and fine musculature. Males reach a weight of 4-6 kg (9-13 lb), while females reach 2.5-4.5 kg (6-10 lb). The head forms a straight triangle with large pricked ears, tapering to a fine muzzle, and features slanted, almond-shaped eyes of deep vivid blue.

Pointed coloration concentrates on the mask, ears, paws, and tail against a pale body, with seal, chocolate, blue, and lilac points accepted by all major registries. Kittens enter the world white or cream, developing their dark points over weeks because cooler body extremities activate pigmentation enzymes. The breed shows an active, demanding temperament and produces a distinct raspy meow to communicate with household members. Grooming takes little effort because the short, sleek coat lacks an undercoat; weekly stroking with a fine steel comb or damp hands clears shedding hair.

Several inherited medical conditions affect the breed. Systemic amyloidosis causes insoluble protein fibrils to build up in the liver and kidneys, resulting in organ failure. Progressive retinal atrophy brings on gradual blindness through photoreceptor degradation in the retina. Cats also show a genetic susceptibility to mediastinal lymphoma, cutaneous mast cell tumors, feline asthma, and GM1 gangliosidosis. Some individuals display compulsive wool sucking or pica, along with congenital strabismus. In addition, these cats have an elevated sensitivity to chemical anesthesia during routine dental or surgical procedures.
