Hello there, Have you tried bitter apple spray or paste? I bought some at both Petsmart and the Ferret Store on-line. It's supposed to be safe and tastes horrible, though one of my ferts likes the way it tastes, he's kinda a strange ferret anyway. Also maybe some Chew Weasels, N-Bones or Foamy Fries would distract them and satisfy the desire to chew. Best of Luck to you. Take care, Suzi and da ferts- Cheechie, Chongie, Goose, Mookie and Ruby [Posted in FML issue 3686]
