Pet's info: Cat | Domestic Mediumhair | Female | spayed | 11 years old
My cat has a sore on the side of his mouth thought to be a rodent ulcer, but the sore it is not responding to treatment (clavimox, depro medrol, steroid injection). What else could be this sore be and what other treatment options are there?

I'm so sorry that you are dealing with this with Vivian. The location is a little abnormal for a rodent ulcer, so I would probably recommend more dermatology diagnostics (especially in an 11 year old cat if she hasn't had problems with this before). That may include a skin scraping or cytology of the area or even a biopsy of the area. Sometimes challenging skin problems require a referral to a veterinary dermatologist for a diagnosis. You can find a veterinary dermatologist near you here. https://www.acvd.org/tools/locator/locator.asp?ids=16_Find_Dermatologist If all results still point to a rodent ulcer, there are other medications you can try that will suppress the immune system. I have included more information on feline eosinophilic granuloma complex below. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=656 Good luck! I hope that was helpful. Thanks for using PetCoach.
