Have the ferrets that have come down with the greenies been vaccinated with a canine distemper specific vaccine? Just a thought - perhaps greenies is a canine parvo strain - if so a 6 or 7 way vaccine could make the difference. I've always vaccinated with 6 way vaccines as I have dogs too and don't want to take any chances with these adorable little creatures. I've not had the virus here (thank goodness) but then again I haven't heard of anyone in our area that has had it either. What do you think? Troy Lynn [Posted in FML issue 0842]
