I have never come across a topical medication that has been effective for treating ringworm in cats aside from prescription-based lime sulfur dips. The concern is that the Microsporum canis (fungal organism causing ringworm) is spread diffusely throughout a cat's entire hair coat, such that an isolated topical spray will not cover all surfaces of every hair, and lead to frequent recurrence. If you are concerned that Baby may have ringworm, she should go to his vet for confirmation and will need to be started on oral antifungal medication. I hope that all goes well!
