Kitties love it! I think I am going to put some Velcro and carpet tiles on it so they have more to grab on to at the platforms too. I like that it is a nice blank canvas and really decent looking compared to those super fugly all carpet ones. So easy to put together and they love the sisal vertical posts to get their scratchies on! They also love napping in the top tower and I really like that it came with a soft bed for it too.
