We took in a older kitten, 5-6 months old, after a short time discovered that he had ring worm. eeeeeeeeeew! Discovered it, because I had noticed I had several round itchy patches on me and just had a hunch that what it was. After taking Zeke to the Vet, Vet concurred the DX. Anyway I wanted to treat it naturally. Walnut oil from Whole Foods store. It worked fabulously! on me too! soaked the sores in it 3-4 times per day. All gone.
