Cat Stomatitis and Chronic Oral Pain

Feline chronic gingivostomatitis (FCGS) is a severe, painful inflammatory condition affecting the mouth that causes immense suffering in affected cats and presents a major welfare challenge.

Key Facts

FCGS affects approximately 0.7-4% of cats and can cause debilitating chronic pain
The condition involves severe inflammation of the gums, cheeks, and throat
Affected cats often show reduced food intake, drooling, pawing at the mouth, and behavioral changes
The exact cause is unknown but involves an abnormal immune response often linked to calicivirus
Full-mouth tooth extraction resolves symptoms in approximately 60-80% of cases

Welfare Considerations

Cats are notoriously stoic and often hide pain, meaning FCGS may be present for months before diagnosis. The pain associated with the condition is severe and persistent, significantly reducing quality of life. Chronic pain causes behavioral changes including reduced grooming, social withdrawal, and aggression. Full-mouth dental extraction sounds extreme but dramatically improves welfare in most cases and should be considered earlier rather than later in refractory cases.
