Is there any new information about ECE - my info is old (from 2000 and 2001) would like to read any new research - Recovered a ferret from this many years ago, but believe I have another with the same symptoms. Also I have a ferret who has a knot at the end of her tail - I think I read about this being a sign of something serious - but cannot remember where - or what. We are going to the vets but would like additional info. [Posted in FML issue 4589]
