One thing that wasn't said clearly enough is NOT to use MINUTE RICE. If ingested, it can swell and cause a blockage. I use pit balls in my ferret room. I find them on ebay. If you look for a while, you will find them for a good price. I buy 100 at the time. When they get grungy, I dump them and start over. I put them in the plastic base of an old cage that is about 20" x 30", and is about 6" high with a scooped out area for them to get in. Katharine Florida [Posted in FML 8012]
