Hello for all I have a 7 month female ferret, and she has fleas. I live in Brazil and I can't find any vet that understand about ferrets. Here in Brazil I have Frontline and Program. Is it safe for use in ferrets? I would like to have the opinion from a vet , if is possible. Erika and Blonda- [log in to unmask] [Posted in FML issue 1701]
