Canine and Feline Medical and Surgical Problems General Information Asthma is a condition caused by constriction of the air passages in the lungs. The exact cause is not known, but asthma probably is a type of allergic reaction.
Some cases are the result of inhaling dust from cat-box litter.
Affected cats suffer episodes of extremely difficult breathing and many have periods of severe coughing. Asthma attacks usually recur and are difficult to predict. Many months may pass between attacks or they may occur several times daily. Important Points in Treatment Mild bronchial asthma is treated medically at home. If the attacks are very mild and infrequent, they may not be treated at all.
