Siamese cats descend from the pointed Wichianmat cats of Thailand, once known as Siam, which appear in centuries-old Thai manuscripts of cat poems. They reached Britain and the United States in the late 1800s and became one of the first breeds recognized by cat registries. Their pale bodies, darker face, ears, paws and tail, and vivid blue almond eyes come from a temperature-sensitive pigment gene.
Many Siamese are talkative, intelligent and intensely people-oriented, following their humans from room to room and voicing opinions about everything. That devotion can turn into loud complaints or mischief when they are bored or left alone for long hours. Adopters who enjoy an interactive cat, and can offer play, puzzle toys and company, often find them deeply affectionate. Shelters also see many Siamese-mix cats with similar coloring and personalities.
