The cat tree is very beautiful and offers some sleeping, cuddling and playing facilities (the climbing rope and the gaming mouse) for cats. However, the structure is a bit complicated, because the spacers have almost all a J (only two with F and two with J + are, all others are J), but not all J are the same length. In addition, one must watch out that one right way up builds the cave, otherwise the ladder can not be built correctly. He is very nice except for the construction, I prefer just to build from a star, otherwise the scratching post, to my sister bought for her two cats each star is worth, it is also the value for money unbeatable. If it is worn out, which is quite normal in use by the cats, always at your back.
