Thanks everyone. I think that my vet, who is a cat specialist, is also getting as frustrated as I am. I only have 2 bedrooms and the rest of my condo is open concept. I also have a hall bathroom. Pearl doesn't get along well with any of her younger brothers and some times she barely tolerates Ziggy & Sky. Pearl, Ziggy, & Sky like to sleep with me at night and so far none of them are showing any signs of infection. I think that separating the cats/kittens would be too hard on them and me. They can be very destructive if they want out of a room. I'm hoping for some definitive results so that my cats can hopefully be treated so this will go away and stay away. If it does turn out to be feline herpes then I hope that my vet will know what I can do to boost their immune systems.
