Feline Pneumonia Study Guide

Overview and Clinical Importance

Pneumonia is inflammation of the pulmonary parenchyma (alveoli and terminal bronchioles) that causes respiratory disturbance, hypoxemia, and potentially life-threatening respiratory failure. While less common in cats than dogs, pneumonia represents a significant clinical challenge due to the diversity of etiologic agents and often subtle clinical presentation in felines.

Cats possess robust protective mechanisms, including a strong laryngospasm reflex, making aspiration pneumonia relatively uncommon compared to canine patients. However, when pneumonia does occur, it requires rapid identification and aggressive treatment. Understanding the various types, diagnostic approaches, and treatment protocols is essential for NAVLE success.

Classification of Feline Pneumonia

Feline pneumonia can be classified by etiology or by mechanism of infection. Understanding these classifications helps guide diagnostic workup and treatment selection.
