Kelly, I'm so sorry to hear this. Ringworm can be very difficult to manage and I sure hope they won't get it. They should be bathed with the special medicated shampoo just in case though. I wish I had a solution for you but I don't. Lots of prayers and positive thoughts are being sent your way. Please take care. (((HUGS)))
P.S. Since Carol does so much rescue work, does she have some kind of an outdoor enclosure where your cats might be able to stay for a little while until you find another place for them? This way they wouldn't be as likely to get the ringworm.
