Interferon is very easy to get in the states. My vet has some frozen but hasn't
perscribed it in years. Go figure. I am getting what he has simply b/c I knew to
ask. I too can't believe your vets haven't even heard of it! Scary! The big thing
now is the feline interferon. It's very new and can't be obtained yet (as far as I
know). The though is that it would be more helpful to cats since it is from cats. I
don't know much a/b it though! Another point of disagreement we have discussed here
is it's shelf life. Most people think it can be kept frozen for a very long time,
others think it "expires" and loses potency after a while. My vet said there is no
evidence that it works for felv or fiv cats, but that since the side effects are so
minimal, he will use it. Hope this helps!
