Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 15 years of experience. I look forward to working with you.
This sounds quite concerning for Arfur. Does he have any symptoms other than no appetite and mouth pain (vomiting, diarrhea, painful abdomen, breathing changes)? Does he have any known medical problems or on any medications right now?
How long has he had these signs (just today, few days, weeks)?
I do advocate that if he seems to be in extreme pain today to have him seen by your local emergency veterinarian. If this is truly mouth pain, then perhaps he has a bad tooth or an ulcer or even a foreign object trapped in his mouth, or has muscular soreness such as can come with myositis.
