Siamese descend from the pointed Wichianmat cats of Thailand, once called Siam, and reached the United States in the late 1800s. They were among the first breeds recognized by cat registries. The pale body, darker face, ears, paws and tail, and vivid blue almond eyes all come from a temperature-sensitive pigment gene, and points often deepen with age.
Most Siamese are talkative, clever and devoted to their people. They like to follow you from room to room and can get loud or mischievous when bored. Many pointed cats in shelters are Siamese mixes, and only pedigree papers confirm a true Siamese, so personality is a better guide than looks. The short, single coat sheds lightly and needs only a weekly brushing.
