This same problem occurred several years ago up and down the east coast. Many ferrets were lost to this "Mystery Disease" My shelter lost five. Now something similar seems to be coming back. I have received some question if I knew anything about Clostridium perfringens Which seems to have been diagnosed in a few of these ferrets and treatment options are being explored. I don't know if this is true or not just what I have been asked about and told. [GT] [Posted in FML issue 4746]
