If your cat is coughing, asthma may be the cause. Untreated asthma in cats leads to chronic scarring of the lungs and a condition that is like Chronic Obstructive Pulmonary Disease (COPD) in people. Diagnosis is made through x-rays with some help from blood tests. Coughing in dogs can be due to heart failure, but in cats, heart failure presents differently - fast breathing rate, weakness, poor appetite and usually no cough. If your cat is coughing, make an appointment with your veterinarian for an exam and testing.
