Feline asthma is an example of respiratory and inflammatory disease.
According to Caswell and Williams in Jubb, Kennedy & Palmer’s Pathology of Domestic Animals (2016): “Feline asthma is relatively common and is defined by the clinical findings of reversible airway obstruction with inflammation. Most cases have an acute onset or recurrent bouts of cough, dyspnea, or wheezing that respond to treatment with bronchodilators and corticosteroids, and are mainly the result of bronchial inflammation, airway smooth muscle hyper-reactivity, and bronchoconstriction.”
The diagnosis of feline asthma is usually made clinically.
