General post: I was talking to Charlie Weiss yesterday and asked him about what he does with ferrets who react to Fervac-D. Charlie says that his first choice is to switch over to Fromm/Galaxy D and that he hasn't seen a ferret yet (although he has only had to do this with a handful of ferrets so far) that reacts to both vaccines. This is somewhat strange, as most vaccines contain the same approximate ingredients, but if Charlie says it works, then it works. With my own ferrets, (here's the "acid-test of my convictions, folks) - I would probably go this way first and do the antihistamine treatment second. But let's make sur to stay at the vet's for 30 minutes afterward anyway. ALWAYS willing to learn new tricks - Bruce Williams, DVM [log in to unmask] or [log in to unmask] [Posted in FML issue 1189]
