Caudal stomatitis in cats: why is it so painful?

Feline chronic gingivostomatitis is a severe inflammatory disease of the mouth. Affected cats can have intense pain even when they continue trying to eat.

The key takeaway

Drooling, foul breath, pawing at the mouth, crying while eating, food dropping, and weight loss are not normal aging signs.

What is feline chronic gingivostomatitis?

It is an exaggerated inflammatory response affecting the gums and oral tissues, often especially severe in the caudal mouth. The exact cause is complex and may involve immune dysregulation, dental plaque, viral factors, and individual susceptibility.

How is it diagnosed?

Diagnosis requires a careful oral examination, commonly under anesthesia, with dental radiographs to assess the teeth and roots. Testing for concurrent disease may be recommended depending on the cat’s history.

How is it treated?

Dental treatment—including extraction of affected teeth and, in many cases, extensive extractions—is a major evidence-based component of management. Pain control and medical therapies may also be used, particularly in cats with persistent inflammation after dental treatment.

Why repeated antibiotics are not a cure

Antibiotics may be appropriate when a bacterial infection is present, but chronic gingivostomatitis is not simply a bacterial infection. Repeated short courses without addressing the underlying oral disease usually do not provide durable control.
