Great idea Cindy and Tom!!! I know that my EmmyLou loves her Ferret Tower, but my boys seem to think they are a bit chunky to climb to the top, so they stay mostly at the openings. They might be more adventuresome with the closer to the floor area on the Ferret Hills and Dales. I like the idea that you also give us a couple different options for purchasing. I've already got several tubes they like, so I'll just get the PVC Kits. Hugs, Florence Love www.craftyweasels.com P.S.
