Melanie, My Kermit had swollen lymph nodes and I was told to expect him to die of lymphosarcoma within a year. However, his bloodwork did not indicate lympho, so he was given further bloodwork which showed up eosinophils in his blood, indicating eosinophilic gastroenteritis instead. I'm sure your Gizmo doesn't have EG, since he is eating and playing well and doesn't have diarrhea, but I do think another test is worth going through to ensure that he gets the proper treatment. Can enlarged lymph nodes also be a sign of infection in ferrets, as they are in people? You clearly want the best for him -- and think of yourself, too! If he does not have as serious an illness, you'll feel wonderfully relieved. Blessings Judith [Posted in FML issue 2143]
