I have a ferret that is 6 years old. She is on pred for insulinoma. Last year she had adrenal surgery on both sides and was doing well. She is adrenal again (swollen vulva) and I put her on Lupron. Lately she has a bout of puss coning from her ear. She was put on medicine and it cleared up somewhat but occassionally still is a bit messy. She is unable to hold her head up straight and walks mostly in circles. The vet mentioned maybe a brain tumor? Does anyone have any other ideas? Thank you, Linda [Posted in FML issue 5239]
