Stormy had ringworm

I took a couple of my cats up to the vet's for their annual shots and got the results of Stormy's culture.
The Vet gave me some pills since she thought it would work better than the salve. It is pretty expensive since she wants her on it for up to six weeks!
But she gets to have canned food with it, which she likes. She is supposed to have it with a fatty meal! Strange.
I am going to try to look it up on the net and see why that is.
The fungus looked yukky that was growing on the culture. Nasty stuff! Still don't know where she got it from.
