It has never happened to me, but whenever I bring in new fosters, the FIRST thing I do is have them vetted. They do not enter my home until then (and if they do, they remain separated)

In the last year I think the rescue has only brought in 3 or 4 cats with FIV or FelV, none with FIP. I kjnow two of the FIV positive kitties came from the same colony. Considering the hundreds we helped this year, thats a pretty small percentage. Jen, correct me if I am wrong.
