I've never shopped at ebay but I've heard that you can get a lot of things for reasonable prices. Good luck if you try this. I got my cats a tower for free. Someone in my building was throwing it out. It has gray carpeting and it looks practically new. They also have two other large scratching posts. You can see part of them in this picture. I bought these at Petco but they were fairly expensive. My babies are worth it though.
