Hello. My vet thought my cat caught ringworm from another cat who had it. He had some spots on him that looked liked it so we treated him with oral and topical medication. My vet also took a culture and sent it out. I took my cat back to the vet yesterday (after 3 weeks) and they said spots look great, but took another culture just to be sure. Well they called me today and said the first culture finally came back and it was negative. Now I'm wondering if my cat had ringworm at all? Do you think I should keep him separate still until the next culture comes back or would it be ok to let him out since the first one came back negative? Any input would be appreciated. Thanks!
