I'm a few days behind on the FML readings, so this goes back a few days. Amy and Debbie were discussing their personal experiences with the greenies. I would like to add an observation. Ferrets which are breeders or at one time were capable of reproduction as adults tend to have less problems with the green virus than ferrets altered at an early date and sold/bought in pet shops. I think - my opinion folks - that this might have something to do with the muscle mass and development of the ferret. Early alters do not develop mass physically as well as late alters. The exception to this are the Manitoba Canadian ferrets. They do not seem to come down with the virus at all. It is my theory, only a thought, that maybe the Canadian ferrets have an immunity - or are the carriers. What I would like to know is this - for those people out there owning Canadian early alter ferrets - have your ferrets been in contact with the green slime, or have your Marshall Farms ferrets become ill while the Canadians have not? Do peoplel in Canada have the green virus?? PLEASE e-mail me at STAR [log in to unmask] with comments or answers to these questions. Once I get a composit, I'll share the results with the FML - no sense cluttering the boards. Thanks, Pam [Posted in FML issue 1217]
