I've had kittens go from negative to positive, and positive to negative. Also had a double+ adult turn out to be only FIV+. His initial snap was said to be a "light" positive and I know that term is highly debatable, but for the record, he did not have a strong blue dot on the first test, but a faint one. He was held for a couple of months, retested on IFA & then snap and was only FIV+.
The kittens who went negative to positive were from a double positive Mom....all kittens cleared the FIV, 2 were only FIV+ when tested (and taken from Mom) at 6 weeks of age, but all turned out to be FELV+. Mom outlived them all. We also had 2 kittens (separate situations, not same litter) who had again that debatable "light positive" on snap tests and were held & retested and were negative, confirmed via snaps & IFA.
