If your cat has mouth sores or ulcers, drools, or struggles to eat, it could be stomatitis — a painful mouth infection. While there is no cure, natural treatments for stomatitis in cats, like coconut oil and probiotic-based supplements, can be used at home to relieve pain, reduce mouth ulcers and support healing. Since 2005, Ask Ariel has helped cats feel better with safe, easy-to-use home remedies to help manage stomatitis symptoms naturally.
"We adopted Trixie from the Animal Rescue League and loved her from first sight! At her first appointment, I told our vet that I was noticing she had bad breath and was a bit lethargic. After checking her mouth, I was told she had Stomatitis. I have had cats all my life and had never heard of this. After discussing treatment options which included steroid shots to extracting all her teeth, I was overwhelmed. How could this be happening? How did this cutie pie develop an autoimmune disease that could be that life altering? I told him that I felt helpless & needed to figure out another option.
I spent hours scouring the internet and found AskAriel. I decided to give it a try. I felt hope! Trixie takes Power Probiotic, Immune Harmony, NOT Drops and QUENT Drops. As she started feeling better, I finally looked at her gums. The AskAriel treatment was working! Subsequent vet visits confirm her Stomatitis is under control. AskAriel has been so helpful during our journey, I am thankful we found them! I believe they truly care and want to help with information & alternative options. I hope Trixie’s story will help others in a similar situation. There is hope and a solution for a better life for your fur baby!"
Our holistic supplements for feline stomatitis target the root causes of inflammation and infection to bring your cat much-needed relief. With probiotics to support digestion and immune-boosting supplements to help calm mouth ulcers and sores, these remedies work together to reduce pain, promote healing, and help your cat feel better.
Immune Support Kit – An effective, easy-to-use cat mouth infection home remedy for managing stomatitis symptoms naturally. Contains three tasteless, natural remedies to help calm infection and inflammation. The Immune Support Kit supplements can be mixed in a small amount of soupy canned food to make them easier to administer. The items in the Immune Support Kit can also be purchased individually.
Power Probiotic – An essential cat mouth sores and ulcers home remedy that promotes healthy bacteria to support immune function. Supporting beneficial bacteria addresses root contributors to inflammation and infection associated with stomatitis, helping manage and prevent mouth sores in cats.
While there is no cure for stomatitis, there are practical steps you can take at home to reduce your cat’s discomfort, support healing, and improve quality of life. Following a consistent plan with diet, supplements, and gentle care can make a big difference.
Make Diet Changes – Cats with stomatitis may stop eating because it's painful. Feeding a hypoallergenic, grain-free canned or raw diet can help reduce inflammation and make it easier for your cat to eat. Avoid kibble and starchy fillers, which can worsen bacteria and irritation in the mouth.
Use Immune & Digestive Supplements – Probiotics and immune-support supplements can work together to calm inflammation, reduce infection, and support your cat’s immune system. These natural remedies are intended to support the drivers behind mouth ulcers rather than only masking symptoms.
Provide Pain & Stress Relief – Keeping your cat’s environment calm and stress-free supports healing and can lessen flare-ups. Some cat owners consider a coconut oil based hemp extract for gentle comfort support.
Maintain Dental Cleanings With Your Vet – Regular check-ups and dental cleanings, along with monitoring for flare-ups or appetite changes at home, can help manage stomatitis long term.
"This is our sweet Daisy girl! Daisy had a severe case of stomatitis that would not clear up. I found and reached out to Ask Ariel on their recommendations. Daisy took the QUENT Drops, NOT Drops and Immune Harmony. I also changed Daisy’s diet using Ask Ariel’s diet tips and info. Daisy is now like a new cat — she is not drooling, not in pain, and is able to eat her food with ease! Thank you for helping our sweet girl live a normal, happy and healthy life!"
Feline stomatitis is an inflammatory condition that causes painful sores to form on the lips, gums and inside of the cat's mouth. It is a progressive autoimmune disease where the cat forms antibodies to its own tissues and attacks itself. In the early stages, stomatitis may appear to be dental disease or gingivitis.
Some cats with stomatitis also develop rodent ulcers (indolent ulcers) on their lips. Since both conditions are immune related, cat owners use similar supplements to treat them.
The most common symptoms of stomatitis may include:
Bad breath (halitosis)
Red, inflamed gums
Mouth sores or ulcers
Cat not wanting to eat (anorexia)
Bleeding from gums or mouth
Plaque and tartar accumulation
"The products at Ask Ariel saved my Ernie's life. He is 7+ years old and has FIV and was suffering with Stomatitis. He was very sick. He wasn't eating anything. I could barely get him to come out. Now he is eating all the time running around like a little kitten. It is like night and day. The people here are so friendly and so knowledgeable — I can't say enough good things about them!!! Even my vet couldn't believe it. She got their information as well."

Stomatitis, also called "tooth plaque allergy," occurs when a cat develops an allergy to plaque on its teeth, triggering inflammation and flare-ups in the mouth. Certain food allergens can worsen this inflammation, and even high-quality grain-free diets may contribute to the condition.
Dry foods contain starchy carbohydrates that convert to sugar, which can weaken a cat’s immune system and contribute to an inflammatory response. Cats with stomatitis often do best on a low-carbohydrate, hypoallergenic, carnivorous diet with soft or novel-protein foods to reduce pain and inflammation. Because each cat’s history is unique, there isn’t a single “best” diet, but diet changes can be important for managing stomatitis, oral health, and bad breath.

"I adopted my 2 kitties, Max and Sasha, who had been neglected in their previous home. Max had a severe case of stomatitis and Sasha had a mild case. For almost a year, Max suffered through rounds of antibiotics and steroid shots just so he'd be able to eat. Then I found AskAriel. I received a food recommendation from Ask Ariel that I was able to find in my local pet store. I also started giving the kitties Power Probiotic for Pets, Immune Harmony, and QUENT. A year later, the vet was thoroughly impressed — no redness, no sores, no buildup on the teeth. I now have two of the happiest kitties on the planet!"
Cats with stomatitis can be especially sensitive and usually don't like their mouth to be touched. This can make administration of supplements challenging.
Easy To Administer – The Immune Support Kit and Power Probiotic are typically the easiest to administer. The Immune Support Kit contains three tasteless liquid remedies, and many cats enjoy the taste of Power Probiotic.
Moderately Easy – Happy Paws Drops are an organic hemp extract in a coconut oil base. Hemp extract has a distinctive odor, so very finicky cats may do better if it’s given with a syringe.
Oral Supplement Syringe Required – Immune Harmony and AllerEaze are herbal remedies and may need to be administered with an oral supplement syringe (capsules opened and divided). AllerEaze can be helpful due to antihistamine properties, but many cats dislike the taste.
"This is Pumpkin who has been using your supplements (Immune Harmony, Power Probiotic, QUENT/NOT and Silver Support Spray), for about 8 months or more. He has Stomatitis, rodent ulcers, and many autoimmune issues. He has not had ANY flare ups since using the products, switching his food, and taking him off steroids. Thank you...He is my angel, and you have given me the chance at giving him the healthy life he deserves."
Happy Paws Hemp Extract – A soothing hemp blend formulated with coconut oil for cat stomatitis. This combination can help calm inflammation that may contribute to mouth ulcers and oral discomfort. Many cat owners report improved comfort and appetite.
Immune Harmony – Plant sterols and antioxidants to help support immune balance and the inflammatory response associated with stomatitis. Supports long-term immune health.
AllerEaze – A natural antihistamine supplement for cats with stomatitis (sometimes described as a “teeth plaque allergy”). Helps support a calmer histamine response and may reduce gum swelling and irritation.
"My name is Topaz. I was diagnosed with stomatitis and it was recommended I had all my teeth removed. My family searched for another option and found AskAriel.com. They helped save my gums by putting a few Silver sprays, Quent & NOT drops on my grain-free food. My last vet check went great — no more stomatitis, though they still need to treat my gums. We’re sticking with the kind, encouraging experts at askariel.com."
Stomatitis vs. Gingivitis – Stomatitis is a severe autoimmune condition where a cat’s mouth reacts aggressively to bacterial plaque, causing painful sores and inflammation. Gingivitis is milder gum inflammation caused by plaque buildup.
Full Mouth Extraction (FME) – FME involves removing all of a cat’s teeth to treat severe stomatitis. While it can reduce pain from plaque, cats may still benefit from digestive and immune support after surgery.
Feline Tooth Resorption – Tooth resorption is when a cat’s teeth gradually break down, causing pain and difficulty eating. Regular dental check-ups are important for monitoring oral health and comfort.

How can I treat my cat’s stomatitis at home?
Natural holistic treatments including diet changes and supplements can help you treat your cat’s stomatitis at home. Stomatitis is a progressive autoimmune condition, where a cat’s mouth develops a hypersensitivity to bacterial plaque. Food allergies and a weakened immune system are thought to be contributing factors and can trigger flareups. Stomatitis, also referred to as tooth plaque allergy – can be helped by reducing the triggers - feeding a hypoallergenic, novel protein diet and using natural supplements to help modulate the cat’s immune system.
Can stomatitis in cats be cured?
Stomatitis is an inflammatory autoimmune condition in a cat’s mouth. It is a progressive condition that can worsen over time. There is not a cure for stomatitis, but holistic treatment can help to manage flare-ups and reduce the severity of symptoms, such as mouth pain, sores, bleeding gums, bad breath, infection and inflammation.
How long can a cat live with stomatitis?
While stomatitis is a painful, chronic condition, holistic treatments can help to manage the symptoms, enabling your cat to live a normal life. Natural supplements combined with a hypoallergenic diet can help your cat avoid stomatitis flare ups, which can trigger bleeding gums, ulcers, inflammation and anorexia. Poor digestion, food allergies and low-quality food all impair a cat’s digestion. Since the mouth is the beginning of the digestive tract, improving a cat’s stomatitis symptoms involves improving the cat’s digestive process overall. Many pet owners have used holistic treatments along with conventional veterinary care from their veterinarian to help their cats with stomatitis live to their full life expectancy.
What is the best diet for cats with stomatitis?
Cats with stomatitis fare best on a hypoallergenic, low carbohydrate diet. Avoiding common food allergens like poultry and grains can reduce inflammation and ease mouth pain.
What does stomatitis look like?
Feline stomatitis inflames and thickens the mucosal tissue in the mouth and gums, resulting in redness, ulcerations, and bleeding in the mouth cavity. It can look like ulcers or blisters. Many cats with stomatitis will paw at their mouths and not want to eat because of the pain. Stomatitis also causes drooling, bad breath and weight loss. Some cats with stomatitis also experience tooth resorption.
