Query: great cat tower - they love it!

This is a great product. I just bought this for my two kittens, and this provides more than enough space for them to explore and climb. Both posts are made up of scratching posts, which is great. The toys in the top have catnip, and they love to wrestle with them, trying to get at it. Really a great buy, and at a great price. Highly recommend.
