Feline asthma should be characterized by paroxysmal episodes of dyspnea. The age of onset is variable, but young adults are commonly affected. There is often an identifiable precipitating event and signs of respiratory distress should resolve rapidly with administration of bronchodilators. Between episodes of dyspnea, radiographic changes are mild. Chronic bronchitis, on the other hand, is a progressive disease that usually affects middle-aged to older cats and is associated with constant bronchial pattern densities radiographically.
Some cats develop bronchitis secondary to, or in addition to, asthma.
