Hi there, This appears very similar to something called a "rodent ulcer" or Eosinophilic Granuloma Complex, but it may be something different, like an infection or a growth. Eosinophilic granulomas are often thought to stem from an overreactive immune system or allergies to insects, a protein in their food, or their environment. Many cases resolve with a course of medication. Some cats need to have strict flea control or a prescription diet. Your vet can tell you more about Chibi's specific case after they do a physical exam. Just in case it is an Eosinophilic Granuloma, here is a link to learn more: https://vcahospitals.com/know-your-pet/feline-eosinophilic-granuloma-complex-in-cats I hope this helps! Thanks for using PetCoach.
