Siamese cats tend to be devoted to their humans, and they can get territorial about them. Siamese cats are energetic, demanding and self-assured. They’re smart enough to be trained, but that doesn’t mean they’ll always agree to it.
If it suits them to learn something, they will, but if it doesn’t, then they’re not interested. They’re known for being extremely vocal, and they’re not shy about letting you know if they’re not happy about something.
