My little Molli has been excessively chewing on her girl part the last couple days, I wiped it with a baby wipe to see if maybe anything was on it but it didn't seem to help. The skin around her girl area is getting red and she seems sad

. I though maybe it was a UTI but she hasn't been peeing or drinking more. She doesn't seem itchy anywhere else. The vet she usually sees is only in on Fridays. Anyone have any suggestions to hold us over until then??
Thnx!
