Stomatitis in Cats: Vet Reviewed Risks, Causes, Signs & Treatments

Cat not eating food

For reasons unknown, cats may develop a painful inflammatory condition in their mouth. This is called stomatitis and may be the result of an overactive immune response to plaque and bacteria in the oral cavity. The typical treatment is to surgically remove some or all of the teeth to decrease the number of surfaces that bacteria can adhere to. Most cats do quite well after the recovery process, with a notable increase in their comfort level.

What Is Stomatitis in Cats?

In medical terminology, the prefix stomat– means mouth, and the suffix –itis means inflammation. Together, these combined words mean “inflammation of the mouth.” Affecting up to 10% of cats, stomatitis is a painful disease involving the gums, tongue, mucous membranes of the oral cavity, and in some cases, the back of the throat1. You may also see feline stomatitis referred to as feline chronic gingivo-stomatitis.

  • Bad breath
  • Drooling
  • Lack of grooming
  • Dropping food
  • Crying out in pain when eating

What Are the Causes of Stomatitis in Cats?

Unfortunately, the causes of this painful and progressive disease remain unknown. It seems to be an underlying abnormality in the cat’s immune response or a heightened immune response to plaque and bacteria on the teeth, but this has not been confirmed. Viruses like feline immunodeficiency virus and feline leukemia virus may also play a role in the development of stomatitis.

How Is Stomatitis in Cats Diagnosed?

Your veterinarian may diagnose stomatitis after performing a thorough examination of your cat’s mouth. Findings may include substantial inflammation and redness of the gums, inside of the cheeks, and the back of the mouth. It is not uncommon for cats to also have periodontal disease and tooth resorption in conjunction with stomatitis.

How Do I Care for a Cat With Stomatitis?

Currently, the best way to treat stomatitis in cats is by surgically removing the teeth. This is done to reduce the oral bacteria and plaque that may be causing an inflammatory response. Approximately 90% of cats diagnosed with stomatitis that have undergone partial or full-mouth tooth extractions have resolved all signs of pain and inflammation, thus increasing their comfort and well-being. Your veterinarian may refer you to a veterinary dentist to perform the specialized surgery.

If your cat normally eats hard kibble, transitioning them to a moist or softened food diet (i.e., canned food) before surgery can help the recovery process, as cats must typically remain on a softened diet for 2–3 weeks after surgery. Your veterinarian will also provide at-home medications to lessen the pain and inflammation during healing. If your cat is reluctant to eat, a medication to stimulate your cat’s appetite may also be prescribed. Once your cat is completely healed, they may transition back to a hard kibble diet if they are willing to eat it.
