we have 4 very large cats that try to get on it. its too unstable for them so we had to take it down. they make it fall over. the little round beds that hang on too the poles are way way too small for a med to a large cat.. so be careful what you buy its very deceiving in looks. the cubbie holes are also way to small for a large cat too even lay down in.. what a shame , and a waste of money ... :-(( for those of you that do buy this for there kittens its ok.. they would have a ball on it. just make sure its attached to a wall or somewhere where it wont fall over.. the base is too small for the height of this product...
