I think that we were all taught that any warmblooded animal can contract rabies and then pass it on. I believed the same thing until my grandmother who is a rehabilitator in Florida taught me different. For some reason rabies in possums is extremely rare and the only two documented cases are lab induced rabies. No wild cases that she was aware of. They also were not able to transmit the disease. It just killed them. This may not exactly apply to ferrets but I do like to add what I know so people have all the facts. [Posted in FML issue 2794]
