Could not put together because drilled holes for screws did not line up properly.  Very wobbly.  Scared my cat Nefer into a panic.  Wayfair refunding purchase.  Suggest more holes, even if not needed so you could reconfigure to suit customers needs.  Also this set up for a kitten, not a full grown cat.  Recommend manufacturer have maximum cat weight in description.  Disappointed the cat tower would not work.
