What is it about dollhouses that is so attractive to cats, apart from all the tiny little objects inside that they can pick up and chew or carry around and then hide for chewing at their convenience? One of my cats took a liking to my childhood dollhouse (pictured below). Years later, after that dollhouse was long gone, I acquired another one and she was right there, ready to curl up in the bottom floor. Lundby probably had no idea that their stable extension was perfectly designed for feline residents!
