Siamese descend from the pointed cats of Thailand, once called Siam, and were among the first breeds recognized by cat registries. The pale body with a darker face, ears, paws and tail comes from a temperature-sensitive pigment gene, and the vivid blue almond eyes complete the look. The coat is short, fine and has no undercoat, so shedding is low to moderate and a weekly brush is usually plenty.
Personality is the main event. Many Siamese are intelligent, vocal and devoted, and they can turn loud or mischievous when bored. Plenty of cats with Siamese coloring are pointed mixes, so a cat's looks don't guarantee its temperament. A home with regular company, puzzle feeders and climbing space gives a Siamese the stimulation it wants.
