Your cat needs to see his veterinarian ASAP. It is possible that your cat has a tooth abscess, severe periodontal disease, something lodged inside the mouth, an injury, or an oral tumor. Regardless of cause, this is a serious medical condition since it is preventing him from eating and drinking normally. Your cat is at risk of becoming dehydrated and developing a condition called hepatic liposis, which can lead to liver failure. Even going 24 hours without food can cause changes in liver functioning.
