This is what I learned recently as well – there are four viral subtypes of the FeLV virus and there is no way to differentiate between them as far as the current tests available to vets. I mentioned this on the forum because I think this may well explain why we sometimes have very differing experiences with the medications/treatments we try. For example, with my little boy Zander, his blood results showed not one even tiny iota of a response to either LTCI or interferon, but others on this forum have had a good response with one or the other of these treatments. If we are dealing with different strains of the virus, this may well explain the different responses to different treatments.
However, I tend to agree with Rachel’s observation that if they cannot currently type which form of virus our cats have, I am not sure how they could tell which is worse. There is probably a basis for this in the research labs, where they may be able to genetically type the viral subtypes, but this may not have been made into a commercially available test yet.

He said that FELV A is less fatal than FELV C. He said there is no way to determine which type of FELV they have. Is it true? I think people on this forum know more than many vets. Thanks a lot
