Built makes the tree then a good impression, through the ceiling tension he is then also very stable. For a small cat but go without. Our cat likes this part well, except for the "hammock" under the top platform, which it has not used and the climb up it has rather disrupted. We have cut out there, only the 4 ropes still hanging and with whom he plays now.
Would choose to date (in this price category) again for this cat tree.
