To ferret proof your bookshelves you may want to try doing what we did to baby proof ours years ago: Stuff the books in so tightly they can't push them out. Also push them to the back of the shelf so they can't get behind to shove them out. I don't know if this will work with ferrets or not. Ours generally don't bother the books too often, though we occasionally have shelf-clearing shelter ferrets. Recently someone has taken to scattering several years worth of Consumer Reports on the floor. Perhaps they were looking to see if raisins were rated anywhere.
