The Applehead Siamese is the popular name for the traditional, old-style Siamese, a sturdier, rounder-headed cat than the long, wedge-headed Siamese of modern show rings. Some registries recognize the type separately as the Thai, while many cats called appleheads are simply pointed cats of Siamese ancestry, so a shelter's label is often a best guess.
Expect a pale body with darker points and vivid blue eyes, plus a short coat that needs little care. In LA, the bigger commitment is attention: these cats are chatty, clever and bonded to their people, and many dislike long, empty days. Plan for daily play, a cat tree by a window and a household where someone is around often.
