Why is my cat's mouth dry and crusty after ringworm treatment?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 2 years and 8 months old | 13.5 lbs

I don't know why my two and a half year old female long haired cat has the equivalent of dry chapped crusty lips in the corner of her mouth. She's dealing with a mild case of ringworm just two spots one on each ear that we've been treating for two weeks now with lime sulfate. It seems to have coincided with that time period. Maybe grooming herself after the treatments? I don't know, it hurts to see her suffer. I'm so obsessive when it comes to their care. I don't know how this happened

Although a picture of it could help to determine more specifically the underlying cause of it, it is likely that the ringworm infection has spread even further and it is now affecting mouth area. I would recommend to start more effective and powerful treatment as anti-fungal medication (even ointment could be beneficial and resolutive). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
