Pet's info: Cat | American Longhair | Female | unspayed | 10.3 lbs
My cat has a super swollen lower lip, and has yellowish patches on the protrusion. It doesnt seem to affect her eating or drinking, but shes been eating more frequently, and it is sensitive to the touch, and seems to be bothering her.

Hello and thank you for reaching out to PetCoach. This looks like what is known as an eosinophilic granuloma, which is a mass of immune cells. Typically these resolve on their own with time, however, this should absolutely be investigated by your primary veterinarian to ensure it is not a more malicious tumor such as a squamous cell carcinoma, which carries a worse prognosis. I've attached a link from Cornell which has more information about cat eosinophlic granulomas for your information: https://www.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information/feline-health-topics/eosinophilic-granuloma-complex I hope this is helpful!
