I'm glad the owners of this house finally admitted the truth ignored by many cat lovers around the world: It's your cats' house—you just happen to live in it too.
Living here would make me nervous, though. I mean, why give those felines a vantage point like that? They will be ready to pounce from above at any time. I can imagine going for a glass of milk to the fridge, in the middle of the night, just to be attacked from above by a couple of them. [Thanks Karl!]
