My kitten has a pink scab, hair loss under jaw. What's wrong?

Updated On September 23rd, 2025

Our kitten had this scab for about less than 2 weeks and there was no way to remove it. I couldn’t see it, only feel it and it kept getting bigger by the day. So I was just able to with a baby wipe and observe her and noticed she’s missing a patch of hair and it’s pink under her jaw. I’m not sure if an older cat attacked her or if it’s something more serious. They’re on flea treatment (no fleas) and deworming medication (1 cat had roundworms somehow). Indoor cat only. Ragdoll/Maine Coon mix.

I would get this seen by your vet to be on the safe side. It may be a healing scab but it looks a little suspicious of ringworm, and that can be easily spread to other pets and people in your household. Another possibility is an allergy to plastic if they have plastic bowls for food or water, but those lesions tend to be located on the chin and lips, not to one side. Your vet will do an exam, probably pluck some hairs from that spot for a fungal culture and may examine some of the cells under a microscope to see if they can identify the cause. Based n these results they should be better able to tell you why this happened and how best to treat it.
