My cats love these new towers. I put one upstairs and one downstairs. They gravitate towards these now instead of the sofa!! Mission accomplished.  Only issue I have is that there is no real area for them to climb or grasp onto when going from one level to the next so it makes it hard for them to find their way into the middle section. But they still really love it. It was the easiest thing ever to put it together and it is very well made and very sturdy. I would definitely buy it again when these ever wear out, which is likely to be a long time from now.
