My cat has ringworm, kitten's symptoms differ. What should I do?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 2 years and 7 months old | 13.5 lbs

Juliet has been diagnosed by the SPCA with ringworm only on the back of her ear. I then show the veterinarian a picture of Spencer my 6 month old's face and they said that looks like ringworm as well. However with Juliet they put the ultraviolet light on the spot on her ear and it did luminesce. They gave me lime dip to treat it with. What Juliet has and what Spencer have look different and Spencer's symptoms are going away on their own however Juliet's are spreading. What do I do?

Juliet may need an oral anti fungal medication to treat her ringworm. The concern is that the Microsporum canis (fungal organism causing ringworm) is spread diffusely throughout a cat's entire hair coat, so that is why it's spreading and oral medications can be used successfully. Ringworm is highly contagious, so Spencer could have it, but it's impossible to diagnose anything from a picture. I'd bring them both into the vet tomorrow. Discuss using an oral anti fungal medication for Juliet, and have the vet check Spencer for ringworm. Keep in mind you need to treat your home as well, as ringworm spores live in it for up to 18 months. I will put a link below on how to do this. Best of luck, I hope this helps! http://www.livestrong.com/article/49666-rid-home-ringworm/
