It's not a good idea to spank ferrets for inappropriate behavior. They are tiny little animals, and one can possible do internal damage - their organs are very small and it doesn't take much of a wollop to hurt them. I scruff mine, tweek their nose, and shout "NO!" very loud. This seems to work for me. Debbie Riccio WNYFLFA Rochester, NY [Posted in FML issue 1641]
