I have a strange and confusing vet story...I have five cats and my friend has five cats too. We both keep our indoors, spay/neuter them and take them to same vet for the last couple of years. Every cat my friend and I've taking in gets tested for FIV and Leukemia before any contact with our other animals. She vaccinated all of hers and I did for all but the last two from the same litter (very stupid I know). A couple of her cats started getting sick (skinny, reclusive, and one with a respiratory problem) but the vet keep saying there was nothing wrong so she went to different vet. He sent some blood work away and here are the results. One FIV+ and Leukemia+, Two cats FIV+, and Two negative for both. After hearing that I got two of my cats retested too at a different vet. One (Vash) was FIV+ he was one of them that was already tested and vaccinated. The second (Bigby) was negative for both he was one of the two that was already tested but NOT vaccinated. Yesterday I finally started looking up information about FIV and happened to find this http://www.aafponline.org/news/statement_felovax.htm

Which says that most diagnostic tests can’t distinguish cats vaccinated for FIV with Fel-O-Vax and those that have FIV. So now I’m really confused?? I called my last vet and he said that Fel-O-Vax was used on Vash and that he would test positive but my new vet said that there are not false positives for FIV. I’m going to talk to my new vet again tomorrow to see what test they did but I was hoping to get an unbiased opinion. Who is right? Has anyone ever hear of this?
