I can't even imagine what you are dealing with. I took in a stray kitten in July 2005, and she had 2 spots of this on her head. She was 2 pounds of energy. All I remember is giving her baths twice a day, putting on ointment, and I think oral meds. It seems to go on forever, but was cleared up in about 3 weeks. Had to make a rush trip to the vet's one morning when I got the special shampoo in her eyes and she held them shut tight for over 5 mintues. Forturnately her eyes were OK. None of the others in the house ever got it. I found dealing with ONE a bit overwhelming! Good luck to you and the cats, get healed up soon!
