The height and width of this cat tree are perfect, however, I did not anticipate the narrow depth. It's perfect size for our 4 month old kittens, but our full grown larger cats aren't interested at all, because there is no room to lay comfortably. The tubes could stand to be about double in length - The kittens can't hardly even fit their whole little bodies in there without hanging out both ends. If the tree were a minimum of 6-8 inches deeper, it would be a perfect addition to any household with a large open wall and playful kitties!
