One of our last foster kittens had ringworm. Even though we kept them quarantined in the bathroom one of my daughters and I both have it. We went to the dr and got some cream. But now our kitten Zoey has one on her ear. The other kitten had pills to get rid of it which I figure we will also get tomorrow. My question is...how do we keep Gracie or anyone else from getting it without quarantining Zoey?
