Have Cat Questions? Ask a Cat Vet Online.
Hello, this is Dr. Jess. I am sorry to hear about your kitty! Has she been tested and found to be a carrier for ringworm?
The treatment of choice in these cases is a combination of oral itraconazole (often must be compounded because human formulations are too large for most kitties) and twice weekly lime-sulfur dips. This will require a prescription from a veterinarian, so if your kitty hasn't yet visited a vet since you have adopted him, you will need to schedule an appointment for him to get this medication. It is also recommended that until a cat has completed treatment and tested negative, it be confined to a separate living area from other cats, and that the room be cleaned twice weekly. You can read about this in detail at the bottom of the first article I am linking.
I am going to attach some links to articles on this condition that will hopefully provide you with some information you may find useful:
