We just adopted a kitten from a rescue and sadly it has ringworm. We have cleaned and vaccummed and have him started on baths with the medicated shampoo, oral antifungal and topical clotrimazole. I just have a few questions. How often do you completely change out the litter in box? Is the dip better than the shampoo? He is quarantined with our other cat a 4.5 year old as they were already together when we found out he had it so it seemed a moot point to separate them. He is only 3.5 months old and cries without his buddy.
