Mike, Last year or so, my Ruby had a very red sore bottom. The vet gave me this cream, actually ointment, called VETASAN OINTMENT. It is prescription (antiseptic) from a vet. an it says consult a vet before use. It worked very well on Ruby. Obviously it was safe for ferrets. I used it almost every day. Maybe this would work for your baby. Just a Thought, Sue Pyron [Posted in FML 8092]
