I bought this for two little kittens, and it has been a good distraction for them. Easy to assemble - no instructions were included, but it's pretty easy to figure out from looking at the box. I had it together in less than 10 minutes. It's not the sturdiest design, but it has held up for a few months so far, and the little ball on a string is even still attached, though the kittens were tiny when they started using it so how long that lasts is questionable. Great for the price though - Wayfair was significantly cheaper than any of the other places I looked that carry this same cat tree, and the shipping was very fast, it arrived within a couple of days even with the standard shipping.
