I just got a call from my vet the test results do not show lymphoma. He believes he has a ruptured lymph duct and the Kylos-effusion is being caused by that. He could do surgery but he doesn't think he could repair it. The effusion could be caused by a coronal virus. This happens in cats and he found only 8 - 10 references to it occurring in ferrets. So he could do surgery but not correct the problem, can't do much to treat a coronal virus, pred may help, but Piccolo is playing and does not seem to be having any problems. If the fluid returns we can have it drawn off again. We're waiting and watching him Thanks Mike [Posted in FML 7835]
