Yes, Siamese cats are very smart. They’re one of the
most intelligent cat breeds out there. They learn routines quickly, figure out how to open cabinets or doors, and can even be taught tricks or to walk on a leash. Their intelligence also shows in how social and vocal they are. Siamese cats tend to communicate clearly with their people, and they don’t like being left out of the action.
That brainpower means they need stimulation (puzzle toys, regular playtime, and interaction), or else they can get bored and start finding their own, sometimes destructive, ways to stay busy. Smart and social, Siamese cats thrive when they have both mental and emotional engagement.
