part of the problem is that we don't know anything about these guys' history BEFORE they come to us--even with young cats, we don't know what diseases/illnesses they've had before, what genetic problems they are carrying around etc. so it's hard to know which is their past and which is the virus... i lost an undiagnosed-til-he-was-in-liver-failure FIV last summer myself--we don't know how old he really was, what his background was etc.... at tthe sanctuary, tho, we saw a DRAMATIC drop in eye and mouth infections once we started giving them lysine...
on one of the FIV lists awhile back, someone talked about how her vet would NOT test her cat for it because the cat, "didn't walk like an FIV cat." that's become a huge joke for all of us--every time we see a huge laidback tom, we say, "yup, must be FIV--walks just like one!" then there's the folks who want to know which cats are the Feline Positive ones.... one really ditzy woman KEPT saying that, no matter how many times we explained..... they had to practically restrain me from pointing out the building where the Canine Positives lived, and the house for the Human Positives, and the barn where the Possum Positives and Raccoon Positives resided...
