Hello Pat, Peterson Ferrets are NOT from Wisconsin. There was a Peterson Ferrets in Minnesota but I do not think he is in business anymore. I do know there is a Peterson Ferrets in Canada. I have three. Two of them have passed on and were able to hear. All three were biters. One of them took almost two years to stop biting me. Till the day he died he would nail my husband. He was a challenge. The one I still have is a deaf blaze. It took me about a week and a half to stop him from biting. Kathy [Posted in FML issue 5055]
