I bought the cat tree for my 2 small Stubentieger, but after 2 weeks of the tree already began to wobble and the lower deck shell is quite Walked and also can not be re-attaching. The extreme susceptibility to berth alongside the Katzenhöle wobbles so hot that one thinks the cat falls right down again. After about 3 months he lößt now slowly altogether. (He falls back into its individual parts)
