My sister told me about an ad in her local newspaper for someone selling a ferret. She called for more information, and the ferret (1.5 years old) has never had any vaccinations - the owners were never told it should have any. My question is, what precautions should be taken if I adopt this ferret (I have three other ferrets--ages 5 and 6--in addition to cats and a dog). If I don't get the ferret, a friend of mine might; he has no other ferrets, but has cats and a dog. Is the risk to our other pets too great to take a chance? Also, how many distemper shots would the ferret need, and how far apart? [Posted in FML issue 3790]
