My 4-month old kitten absolutely LOVES this cat tree!!! He’s playing with it all the time or just hanging out in the condo or one of the nests. He’s quite rough on it (scratching and climbing continuously) so hopefully the tower will hold up. The instructions were pretty clear on how to put it together and it didn’t take a long time and it’s really sturdy. We haven’t pinned it to the wall but so far it’s still standing, it’s massive and tall enough. Money well spent.
