Dr. Williams: I have a 5 year old female who had surgery for insulinoma and left adrenal two years ago. The insulinoma has returned and I suspect the right adrenal. I had made the decision to not do another surgery because my vet has retired and decided to put her on prednisone about 2 weeks ago. Is it now "impossible" to have surgery done after she has been on pred or can I change my mind if I decide I want it done? Or after the use of pred does it suppress the immune system so much that it is not a good idea to go through surgery??? Also, just wanted to let everyone know that I have owned 6 ferrets over the past 10 years and they have all been vaccinated with FERVAC with no reaction. Hope this will help to determine a percentage. I am so grateful Dr. Williams, that you are on the FML. I look forward to your posts every day! Thank you for being so accessible to the ferret community. Thanks! Paula and her two fuzzies in Salem, Oregon [Posted in FML issue 3241]
