Absolutely outstanding quality, shipping, packing and size. My Siberian cats LOVE THIS CAT TOWER! We have another one by the same company in the 72 inch size, both are excellent! The sissel posts are great providing plenty of scratching joy and the sizing is just right...the base is sturdy and strong, as are the screws, and everything is safe for our cats. It is large yet compact so that it doesn't take over the room but fits nicely in the corner by the window. I highly recommend!!! These are WAAAAY better than the overpriced garbage sold at other pet stores. Go with WayFair and this manufacturer!! Excellent can't say it enoug!
