FIV seems to be endemic in southern Westchester. We've had several false positives from there; the kittens probably had antibodies from the mothers. Western Blot tests, while slow and expensive, are very good for confirming the results. The kittens in question did throw off the virus and tested negative at 6 months.

If we followed the one year old protocol, we would not be able to adopt a single kitten. Many vets in our area will test at 8 weeks, but call the results "at risk" and say they are not 100% accurate. Well, no test is.
