Why don't you read through the issues of Modern Ferret, Ferrets or Ferrets USA that the pet shop sells and find an article on why shavings are bad for ferrets? It seems to me that it is mentioned at least once every other issue. If you point out a published article, it might have effect. The other option is to get your vet involved to call and talk to the pet shop owner about proper ferret maintnenance while in the pet shop. I'm writing an article for HSUS on ferrets in pet shops. It may not get published, but hopefully it will help out animal control people who investigate complaints about ferrets in pet hsops. Pam T. [Posted in FML issue 2912]
