Feline Asthma

Feline asthma is an allergic respiratory problem affecting at least one percent of cats. This condition can range from mild to severe cases and symptoms can come and go.

When your cat experiences an asthma attack your cat begins to wheeze or cough and may show other signs of breathing difficulty. The muscles around your cat’s airways tightens and block their airflow. The airways swell and produce more mucus, which make the airway even narrower, and cause your cat to have a difficult time breathing. Below we will discuss the causes, symptoms and treatment options of asthma in cats.
