The kids are fine now, and I got an apology from DD. I did find a lot of info on the web about this, and they understand now. The other three are getting tested tomorrow morning, but we made the decision that even if one or all are positive, we aren't putting anyone down until they show signs of being sick. Two of my cats are senior citizens, and I certainly am not going to do anything rash.
Glad to have all your shoulders to cry upon!!
