Dang it all; three ferrets are starting to cough a little and mouth breathe. I've had the flu for a few days (Not a nasty one for me -- so I've been lucky.) and was very careful to avoid the ferrets, but it looks like I may have managed to infect them before I knew I was ill. Time to separate and take action. Poor furries; they won't be likely to already have built up antibodies. [Posted in FML issue 2132]
