Synonym: feline allergic bronchitis
Pathology very similar to COPD/SPA-RAO in horses and human asthma, although few published papers relating to it
Allergens - house dust mites, fungal spores
Widespread narrowing of airways
- Extrinsic asthma
  - Type I hypersensitivity in response to allergen challenge - mediated by IgE
  - Pathological changes:
    - Exudate into airways - mucus/ cells
    - Thickened airway walls - oedema, glandular and smooth muscle hypertrophy, vascular congestion
    - Altered fluidity of mucus (associated with goblet cell hyperplasia) -> less effective mucociliary apparatus
- Intrinsic asthma
  - A proportion of cats there is an increased propensity for the bronchial smooth muscle to contract (increased bronchial reactivity) -> airway constriction
