🐾 Vet’s Guide to Brachycephalic Airway Syndrome in Cats: Causes, Symptoms & Treatment in 2025 🐾

By Dr Duncan Houston BVSc

Brachycephalic Airway Syndrome (BAS) is a condition affecting flat-faced cat breeds, leading to breathing difficulties due to anatomical abnormalities. This comprehensive guide provides Australian cat owners with up-to-date information on the causes, symptoms, diagnosis, treatment, and prevention of BAS in 2025.

🔬 Understanding Brachycephalic Airway Syndrome

BAS encompasses a range of upper airway abnormalities resulting from the shortened skull structure of brachycephalic breeds. These abnormalities can include:

• 🐾 Stenotic Nares: Narrowed nostrils that restrict airflow.
• 🐾 Elongated Soft Palate: Excess tissue that obstructs the airway.
• 🐾 Hypoplastic Trachea: Underdeveloped windpipe leading to airflow limitation.
• 🐾 Everted Laryngeal Saccules: Tissue protrusion into the airway due to increased effort in breathing.

🐱 Recognizing Symptoms

Symptoms of BAS can vary but often include:

• 🐾 Noisy breathing or snoring
• 🐾 Open-mouth breathing
• 🐾 Exercise intolerance
• 🐾 Heat sensitivity
• 🐾 Gagging or coughing
• 🐾 Cyanosis (bluish gums)
• 🐾 Collapse during exertion

🧪 Diagnosis

Diagnosing BAS involves:

• 🐾 Physical Examination: Assessing facial structure and breathing sounds.
• 🐾 Imaging: X-rays or CT scans to evaluate airway structures.
• 🐾 Endoscopy: Visual inspection of the airway under anesthesia.

💊 Treatment Options

Treatment depends on severity and may include:

• 🐾 Surgical Intervention: Correcting anatomical abnormalities.
• 🐾 Weight Management: Reducing excess weight to alleviate breathing effort.
• 🐾 Environmental Control: Keeping the cat in a cool, stress-free environment.
• 🐾 Medication: Anti-inflammatory drugs to reduce airway swelling.

🛡️ Prevention Strategies

Preventing BAS involves:

• 🐾 Selective Breeding: Avoiding breeding cats with severe brachycephalic features.
• 🐾 Regular Veterinary Check-ups: Early detection of respiratory issues.
• 🐾 Maintaining Healthy Weight: Preventing obesity-related complications.

📍 Considerations for Australian Cat Owners

In Australia's warm climate, brachycephalic cats are at higher risk of heat-related complications. It's essential to provide a cool environment and monitor for signs of respiratory distress, especially during hot weather.
