We have a ferret showing some potentially very serious liver problems. External symptoms are lethargy, diarrhea, and rapid weight loss, with some hind limb weakness. We think it could be related to a recent distemper vaccination, although viral infection has not been ruled out. Has anyone else had unusual distemper vaccination reactions this year? I don't mean allergic reactions that show up within the hour of the shot, but unexplained illness in the following weeks. If you have seen distemper vaccination reactions like this in the past few months, please contact me. I would like to know what you saw and what your vet did, as well as the name of the vaccine. Also, if you have seen viral liver infections, i would appreciate hearing more about it. Thanks, Jacqueline [Posted in FML issue 2621]
