I'm so sorry about your little ferret. We also have ferrets and I have to tell you they are real heartbreakers Ferrets tend to get lots of illnesses and they hide them well till they are very sick. I think I've cried buckets over my dear sweet ferrets over the last 9 years. We currently have 2 girls and both are adrenal and getting Lupron shots. One has had both adrenal glands removed but is still symptomatic. I'm not sure we'll get any more sweet ferrets when the last 2 are gone (hopefully not for a long time)
