My cats seem to really like it. I am a little nervous because the top does seem to sway some and my 2 cats do not reach the 40lb recommended weight limit, but the base does seem stable. As of right now it is slight swaying and other than that I love it. My cats use all of the podiums and cat condos. Also, I have 2 adult cats so it seems to be large enough not just for kittens even though the podiums are a bit small for my fatter cat.
