My kitties think they have died and gone to Kitty Heaven.   I've never seen them happier or having more fun....be it a lone kitty adorning their new "home" or two of them playing on it, I must admit it has given both my kitties and myself endless hours of enjoyment.   Some have stated that it is "wobbly" however I feel for something of this type it is as secure as I would expect.   Any time you have a 10lb plus feline jumping on top of a perch unless it is a solid piece of wooden furniture it is going to wobble.   The fact that they feel secure and I have it against a wall, I know that they will not get hurt, that is, unless their own antics make them fall off the edge!!!   I could not be happier and would highly recommend this tree house to anyone.
