Even though this wasn't directed at me I thought I'd give my input (my husband says I do this all the time - LOL). The only way I think this would be possible is if the virus is in transition. Like, it has just gotten into the body and it hasn't had time to do what ever it does to get into the blood stream. The ELISA test and an IFA test would be negative at this point. I'm not sure if the cat can pass it at this point though since it hasn't really gotten into the saliva or bloodstream. Not sure about that but it seems logical to me. Then the virus progresses and gets into the system/bloodstream or saliva and the ELISA test would be positive but the IFA test would be negative. I'm guessing at this point the cat could spread it. After this if the cat can't extinguish the virus or put it into latentcy then it gets into the white blood cells and the IFA test would eventually test positive. The cat could definitely pass it at this point. I did for sure read that if the virus if put into latentcy then it is carried in the bone marrow but not in the white blood cells or bloodstream or saliva so it can't pass the virus to other cats. That's my thoughts but I'm not a vet. I know that if it's in latency they can't spread it which I found very interesting. The cat wouldn't test positive at that point either, even on the IFA test.
