Bought this second cat tree for our 3 newly adopted cats. The first one was for our 1 existing cat that are still a little scared of them. I like how all the posts made of and this tree is really sturdy. One of the adopted cat we have is on the bigger side and he always the one hanging out on this one. I modified one of the posts where the circle perch attached, instead putting it at the very top, I put it lower center part.
