Asthma or bronchitis is a fairly common condition affecting cats. It occurs as a result of the airway being hypersensitive to certain stimuli, resulting in airway constriction, excess mucus production, and air trapping. Diagnostics include a physical exam, blood tests, x-rays, bronchoscopy, and bronchial or tracheal lavage. As asthma cannot be cured, treatment is aimed at the management of the disease using a combination of steroids and bronchodilators. Adjunct treatments include modifying the environment to reduce exposure to the noxious stimulus, hypoallergenic diet trials, and acupuncture.
