Online vet, Dr. Marie

Dr. Marie replied:

Sorry to hear that Autum is having problems with rodent ulcers (also known as eosinophilic granuloma complex). Is Autum receiving oral or injectible steroids?

I usually find that one (sometimes two) injections of steroids will almost always take care of this problem. However there are some cats that become resistant to steroids for this problem.

Your vet can help you decide on an alternative treatment, but some options include:


  • A topical steroid (assuming the lesion is in an area where you can put a cream or steroid drop)

  • Topical tacrolimus which is an immunosuppressive medication.

  • A medication called cyclosporin or atopica - It can be a little pricey, but often works well.

  • If the lesions are more on the inside of the mouth, you may be dealing with feline stomatitis. Often these cats do well with full mouth extractions.



I hope things are ok soon!

Dr. Marie.
