Do Siamese cats bond with one person?

Yes, Siamese cats often form a strong bond with one person in the household. They’re extremely loyal, affectionate, and people-focused, but that attention can center heavily on one favorite human. Although they usually get along well with everyone, they tend to follow their chosen person from room to room, talk to them constantly, and even try to sleep as close as possible.
This deep attachment is part of what makes Siamese cats so special, and sometimes a little clingy. If their favorite person is away often, they may become anxious or needy, which is why companionship (either from another pet or more human interaction) can really help them.
