The reason why you need to adjust your cat's diet when they have oral problems is that the inflammation may be caused by improper food. For example, if the cat eats food that is too "heaty" (causing internal heat), it may experience a series of inflammatory problems due to internal heat. Therefore, cat owners should change their cat's diet at this time, such as millet porridge or vegetable porridge that is easy for the cat to swallow, and provide plenty of clean water for the cat to drink. 
The cat's problem might be due to a lack of proper oral hygiene. Cat owners should remember to clean their cats' teeth weekly and regularly use oral hygiene sprays like Pet Mouthwash. Although cats are pets, it's still important to pay attention to certain aspects of their health.
Supplement vitaminsCats often develop mouth ulcers due to a vitamin deficiency, especially vitamin B. In such cases, owners can supplement their cats' diets with vitamin B by feeding them carrots, spinach, apples, and other vitamin B supplements. Combining these with a pet oral ulcer treatment can also help the cat absorb nutrients quickly and recover.
Take antibioticsIf the above methods do not improve the cat's drooling and bad breath, the owner can give the cat antibiotics such as amoxicillin to reduce inflammation, or take the cat to a veterinary hospital for antibiotic injections. This is a temporary solution to help relieve the cat's symptoms, but it is not a long-term solution. The owner should still pay attention to the cat's care in the future.
