Cat stomatitis requires cleaning of the mouth and anti-inflammation. It is best to take the cat to the pet hospital to choose pet-specific anti-inflammatory drugs, which will have better effects. During the treatment of stomatitis, you should also pay attention to the cat's diet. Don't feed the cat too hard food. Try to feed the cat some food that is easier to chew and digest and less likely to remain in the mouth. You should also clean the cat's mouth and apply medicine on time, and at the same time, supplement B vitamins.
