I think the positive cat may not be contagious until the
virus activates. Then she will shed it and infect the others.
My vet didn't know if a cat is contagious while the virus
is still latent. But I know this, Henry Lee's virus activated
after he had anesthesia for a dental, but it didn't affect
him when he was neutered a year earlier. He became
ill and died a month later. I think Phillipe and Katyushka
were infected during that month. So I'm guessing that
while a positive cat's virus is latent, he or she may NOT
be contagious. But you may not know right away when it
activates and is infecting your other cats.
