I'm thinking about getting Advantage or Program for my ferret to solve the flea problem she is having. Could one of the vets or assistants on this mailing list please send me an email with information on what is in these products and how they act in the ferret's system to rid them of fleas? I would really appreciate it. Debbie Pixie (Mommm, I am *so* sick of these itchy things....) [Posted in FML issue 2139]
