I would like to reiterate what another ferret owner posted yesterday: Kits from Marshall Farms have only had one distemper shot and they still MUST HAVE two more. In my experience, however, because there have been reports of other breeders using the same or similar ear tattoos as Marshall Farms, I do not assume that pet store kits have had ANY vaccines. That's why my ferrets always get three distemper shots -- I'd rather be safe than sorry -- followed at the appropriate age by a rabies shot. In fact, given the propensity toward human error (including my own), I would probably take ferret kits to the vet for three distemper shots even if I bought them from a reputable breeder. It isn't worth the risk to me to save $15 or $20. Linda [Posted in FML issue 2751]
