Melissa, Maybe this will help. We've had two ferrets with adrenal tumors. One responded to Mitotane, an oral chemotherapy drug. Our vet obtained this from a local hospital. It shrank the tumor. The other one had to go for surgery 2 years ago and has done well. However, now he is starting to show signs of adrenal failure. We've just started him on adrenal-support herbs: bee pollen, royal jelly, spirulina. We got this info from a herbal book called: Herbal Pharmacist, by Linda Page. We think it's helping him. We have an old ferret that just got sick. None of the vets could figure out what his problem was/is, so we resorted to herbs. We started him on Valerian for pain relief and sedation. It helped almost immediately. We also started him on Mullien for asthma-like problems, several vets thought the problem could be allergy. He is breathing a lot easier and looking and acting a lot better. Also we put humidifiers in the room the little guys sleep in. If vets can't help, go to a local herb store and maybe you can ease Gypsy's symptoms a little, I've heard of some miraculous cures using herbs. Caroline [Posted in FML issue 2553]
