My two kitties Larry and Gonzo love it! And when we kitty sit their brother Cooper they have even more fun! It feels sturdy and so soft! The 2 hanging play balls didn’t last long but we figured that would be the case as our rambunctious group are rough on toys! Great purchase! Fun to watch them play on it! My 20 year old son had it put together in a couple hours, no problems. They aren’t to sure about using the lowest level hammock but time will tell.
