Hi Beth,
I'm sorry to hear about your situation, though I think it's great
that you took the time to take care of the little ones. You've
certainly come to the right place for thoughts on what's going on.
There are a number of rescuers on the list who will have good advice
for you (and they'll do much better than I could). I will say that it
seems unlikely that Blue would have picked up FeLV from the less-than-
intimate contact with the kittens. If Blue is over a year and a half
old, and is healthy, I seriously doubt she would contract the disease
and remain positive. Even if she's younger than that and not in great
health, it sounds like she didn't have any close interaction with the
kittens. That's my lay-person's opinion. I hope you're able to find
homes for the kittens.
