Great item! Looks cute, pretty easy to assemble, and my kitties love it. I got them to start using the condo by luring them with treats, now there is a cat in it daily! 

To answer concerns about the bars being in the way and hitting cats’ backs…it’s kind of true but kitties learn! Cats can moved from one step to the next either from the front or the back (behind the bar). Unless your cat is super chunky and unable to maneuver themselves it’s not really an issue
