Brachycephalic obstructive airway syndrome, or BOAS, is a breathing condition that can affect flat-faced cats, such as Persians and Exotic Shorthairs, just like it affects flat-faced dogs.
Their shortened facial shape can make it harder for air to move normally through the upper airways and lead to:
👉 Noisy breathing
👉 Snoring when awake or asleep
👉 Open-mouth breathing
👉 Exercise intolerance
👉 Breathing difficulties in warm weather or during stress
👉 Gagging or retching
BOAS can have a big impact on comfort and quality of life, even if the signs seem mild at first.
BOAS diagnosis is based on your cat’s history, examination, and sometimes further assessment of the airways.
Treatment depends on severity, but may include weight management, reducing stress and heat exposure, and surgery to help improve airflow.
If your cat struggles with breathing or seems noisy when resting, it is worth booking a check-up with us.
