Stomatitis is a painful inflammation of a cat's mouth and gums. It is a progressive autoimmune disease where the cat's mouth and gums develop a hyper sensitivity to bacterial plaque (also called Tooth Plaque Allergy). The cats suffer from red mouth sores and swollen, inflamed gums. Feline stomatitis natural treatments include a change in diet and using a few home remedies. Stomatitis symptoms can improve by feeding a hypoallergenic, low carbohydrate diet with immune support supplements to calm inflammation, infection and allergic reaction. The Immune Support Kit, , AllerEaze and Immune Harmony have been especially helpful.
