Well I have two boys with ears like that. I think it is from a hematoma on the ear (big blister thing). Of course, I have just assumed that since the same thing in a dog has similar affects. I just use epi-otic ear cleaner for them and they are pretty good. Sampson's is curled up so tight I can't begin to clean it otherwise. I have had both ferrets since they were young. Oh for the record, Freds is a MF and Sampson is from a private breeder. Blessings, Maggie [Posted in FML issue 4049]
