Our cat loves this he was a ferel cat who decided to come in doors so we created his own space for him in the utility room he easily got to the top and loves it We hear  him climbing and jumping when he thinks we can’t see him and it was so easy that I put it together myself with clear instructions I could follow . My older cat loves it too and climbs as high as He can but he is a very large boy and doesn’t feel safe going right to the top
