Asthma Symptoms in Cats
Feline asthma-very similar to human asthma-is a chronic inflammation of the small passageways of a cat's lungs. When an asthma attack occurs, these passageways thicken and constrict, making it very difficult for a cat to breathe. This often leads to respiratory distress, which can become grave in a matter of minutes. The lungs may also begin to discharge mucus into the airways, leading to fits of coughing and wheezing. Some cats with milder cases only experience a slight, chronic cough. Because asthma can quickly become a life-threatening health problem, any coughing cat needs a veterinary evaluation.

What Causes Asthma in Cats?

Common factors that can contribute to the severity of an asthma attack include:
Asthma-like symptoms in cats can also be associated with other disease, including heartworm, respiratory parasites, tumors, heart failure and pneumonia.
