==Description==
 +
Feline asthma is an allergic airway disease that bears many similarities with asthma in humans and with [[Recurrent Airway Obstruction|recurrent airway obstruction]] (RAO) in horses.  Affected animals become allergic to allergens present in their immediate environment, including house dust mites and fungal spores and produce [[IgE]] antibodies against these molecules.  When later exposed to the same allergens, asthmatic cats suffer a form of type I hypersensitivity response localised in the bronchi and bronchioles and resulting in constriction of the airways.

Cases of feline asthma may be divided into '''intrinsic''' and '''extrinsic''' disease.
