I think my cat has Eosinophilic Granuloma of the lip (upper lip ulcer/sore). But I can't be certain. She has nothing else wrong, and her tongue is okay. We can't afford to take her to the vet, so I was wondering if there is a home treatment that could be given to her (I read that a cortisone treatment (shots) usually works if its simple). If its not available to do at home, is it really costly to get it done at the vet? I realize all vets are different.
