If you have a cat tree, do your cats use it?

I bought my 7' cat tree on ebay as well as the similar smaller looking one that I put next to it. The rest I either bought at cat shows,Big Lots, or pet stores. Here are a few old pictures of them. I've had the 7' cat tree since Jan.2003 and I got the smaller similar looking one a little while after that. Both are still going strong. I've only had to add some sisal rope to them.
