Siamese cats trace back to the pointed Wichianmat cats of Thailand, once called Siam, and they were among the first breeds recognized by cat registries. They're medium-sized, long and lithe, usually 6 to 14 pounds, with a short, fine coat, a darker face, ears, paws and tail, and almond-shaped blue eyes. Lifespans commonly run 11 to 15 years, so adoption is a long commitment.
Personality is the main draw and the main challenge. Many Siamese are talkative, intelligent and closely bonded to their people, and they can turn loud or mischievous when bored. Plenty of cats in shelters are pointed mixes rather than purebred Siamese, so coloring doesn't guarantee a cat's temperament. Every cat is different, and a calm adult may be quieter than the breed's reputation suggests.
