 Feline Asthma

Asthma is a chronic disease that affects the lungs and lower airways.

The airways become thick, and mucus production increases, which constricts the airways. This makes it difficult for the cat to breathe.


Asthma sometimes develops spontaneously for no known reason. Other times, it is an allergic reaction from inhaled irritants (cigarette smoke, dust, perfume, etc.).


Asthma can turn into a respiratory crisis. Sudden breathing difficulty due to narrowing of the airway can be life-threatening. If you notice any of the above signs, call your veterinarian immediately.


Your veterinarian will perform the following tests:

Cats with asthma usually need lifelong medical treatment. Your veterinarian will probably reduce doses gradually.

As asthma is a chronic condition, complete control may not be possible, but with the proper treatment, your cat can enjoy a good quality of life.
