This cat tree is wonderful. My cats love it. At first they sniffed around it and looked at it and then my patches jumped up on the first small platform and that was it.  I love to watch them play, it just makes me happy. If you have a cat, or multiple cats, this is the tree to buy. You will love it more than your kitties. It is easy to put together and although I could see how big it is here, I was still amazed to see it in my house. Wow, it is big and tall. So far, no cons. Thanks Wayfair for another great product.
