Hi, my name is Sandy and I have 2 ferrets. They have fleas. I have shampooed (with flea shampoo) them twice in one week, changed all their bedding, washed the whole cage but they still have them. How much can I shampoo them without hurting them? Should I just keep shampooing and washing their bedding until they (the fleas) are gone or should I take my ferrets to the vet? I heard advantage works well. I don't know what to do. Please e-mail me or post to the list. Thank you, Sandy, Schnookie, Lottie & fleas [Posted in FML issue 2428]
