Last week I took Ben and Jerry (age 3.5) to the vet for their annual exam and vaccinations. Dr. Stacey Di Maria said that Ben has some enlarged lymph nodes and should be reexamined in a month. I am very concerned about this because I have read about ferrets with lymphosarcoma. I would appreciate some information on how this disease is diagnosed and treated in ferrets. What is the likelihood that enlarged lymph nodes are from a benign cause? If it does turn out to be lymphosarcoma, what is the prognosis? Also, Ben and Jerry both vomited several times after their shots. (They got rabies and distemper shots.) I stayed at the veterinary clinic for about an hour until they stabilized. Jerry, who had the strongest reaction, was given an antihistamine shot. Has anyone else seen this happen to their ferrets? Any theories about why this happened and how it could be prevented next time? Clare Sebok [Posted in FML issue 0486]
