Someone mentioned (some time ago) using the tension-type curtain rods in front of books to keep them in place. Sounds like a great idea to me. Mine don't tend to get into the books too often so I just pick them up and put them back. Of course, I make sure expensive or very old books are totally out of their reach. I'm allergic to cats (which is terrible because I love them) but have had no problems with ferrets. My cat allergy started after I was in my 20s. Until then, I had always owned cats. Before I got my first ferret, I went to a pet store and played with one for an hour or so just to make sure I wouldn't react to them.
