🚨 Emergency Warning
Feline stomatitis is a severe inflammatory disease of the oral cavity. If left untreated, it can prevent cats from eating, ultimately leading to death from malnutrition or dehydration. Many cat owners mistakenly believe that bad breath is just a minor issue, unaware that it can be an early sign of feline stomatitis.
Feline stomatitis is a chronic, progressive inflammatory disease affecting tissues such as the gums, tongue, and oral mucosa. In Hong Kong, the prevalence rate is approximately 0.7% to 4%. However, because early symptoms are easily overlooked, the actual number of affected cats may be much higher.
As the professional veterinary team at the Hong Kong Social Enterprise Veterinary Hospital (HKSEV), we have treated over 500 cases of feline stomatitis in the past decade. According to our clinical statistics, the cure rate for cats diagnosed and treated early can reach over 85%, but the mortality rate for delayed treatments can be as high as 30%.
🔬 In-Depth Analysis of the Causes of Feline Stomatitis
1. Abnormal Immune System Response
The primary cause of feline stomatitis is an overreaction of the cat’s own immune system to normal bacteria inside the mouth. Normally, a large number of commensal bacteria live in the oral cavity, but in cats with stomatitis, the immune system mistakenly views these bacteria as a threat, triggering a continuous inflammatory response.
Immune Response Mechanism:
- T-cell Mediated Response: Massive accumulation of CD4+ and CD8+ T cells in stomatitic tissues.
- Cytokine Storm: Excessive release of inflammatory cytokines such as IL-1β, TNF-α, and IL-6.
- Tissue Destruction: Persistent inflammation leads to damage of the oral mucosa and gingival tissues.
2. Viral Infection Factors
Multiple viral infections can trigger or worsen feline stomatitis:
- Feline Calicivirus (FCV): The most common inducing factor; approximately 60% to 80% of cats with stomatitis carry this virus.
- Feline Herpesvirus-1 (FHV-1): Causes oral mucosal ulcers; about 30% to 50% of affected cats are infected.
- Feline Immunodeficiency Virus (FIV): Weakens the immune system, increasing the risk of stomatitis.
- Feline Leukemia Virus (FeLV): Impairs immune function, making cats more susceptible to stomatitis.
3. Dental Disease Complications
Oral diseases such as gingivitis, periodontal disease, and dental caries provide a breeding ground for bacteria, intensifying the inflammatory reaction. The accumulation of dental plaque and tartar continuously irritates the gums, creating a vicious cycle.
4. Genetic Predisposition
Certain breeds—such as Persians, Siamese, and Maine Coons—exhibit a higher incidence of stomatitis, indicating that genetic factors play a significant role in the development of the disease.

- Wound Closure: Suture the gums using absorbable sutures.
- Postoperative Care: Pain management and anti-infection treatment.
3. Supportive Treatment
- Nutritional Management: High-calorie easily digestible canned food, served at room temperature and textured appropriately (mashed or liquid). Tube feeding if necessary.
- Environmental Management: Provide a quiet, comfortable environment, reduce stressors, keep food and water bowls clean.

🎯 Conclusion: Never Ignore Your Cat’s Oral Health
Feline stomatitis is a serious yet treatable disease. The key lies in early detection and professional treatment. As a cat owner, your careful observation and timely action can save your beloved cat’s life.
Remember, bad breath is not a minor issue, and drooling is not normal. When you notice any abnormal oral symptoms in your cat, do not hesitate—seek professional veterinary assistance immediately.
Q1: Is feline stomatitis contagious to other cats?
Feline stomatitis itself is not directly contagious, but the viruses that cause it (such as Feline Calicivirus and Feline Herpesvirus) are infectious. It is recommended to temporarily isolate the affected cat and keep the environment clean. Other cats should undergo health check-ups and vaccinations.
Q2: Approximately how much does the treatment for feline stomatitis cost?
Treatment costs vary depending on the severity of the condition. Conservative treatment (drug therapy) ranges from approximately HK$2,000-5,000; full-mouth tooth extraction surgery ranges from approximately HK$8,000-15,000, which includes pre-operative examinations, anesthesia, surgery, and post-operative care. We provide detailed treatment plans and cost estimates to ensure transparent pricing.
Q3: How can the recurrence of feline stomatitis be prevented?
The key measures to prevent recurrence include: regular oral check-ups (every 6 months), maintaining good oral hygiene, avoiding stressful environments, providing premium nutrition, and staying up to date on vaccinations. For high-risk cats, long-term immunomodulatory therapy may be necessary.
Q4: Can feline stomatitis be completely cured?
Mild stomatitis can be completely cured with proper treatment. Moderate to severe stomatitis may require long-term management, but symptoms can be well-controlled. Full-mouth extraction is the most effective treatment for severe cases, with a cure rate of up to 90%. Early detection and treatment are crucial.
Q5: I have multiple cats at home; how can I prevent the spread of the disease?
Recommendations include: 1) Temporarily isolate the affected cat; 2) Do not share food and water bowls; 3) Regularly disinfect the environment; 4) Have all cats undergo health check-ups; 5) Ensure vaccinations are complete; 6) Perform health screenings for new cats before they move in. These measures can effectively reduce the risk of disease transmission.
