Abstract: This study conducted a comparative analysis of the respiratory system of three feline species: Leopardus pardalis (ocelot), Leopardus tigrinus (margay), and Felis catus (domestic cat), with the aim of identifying structural similarities and proportional differences relevant to veterinary medicine and species conservation. The cadavers were dissected at the Animal Anatomy Laboratory of UENP, where identification, measurement, and opening of the thoracic and abdominal cavities were performed, followed by the removal and isolation of respiratory structures such as the tongue, larynx, trachea, and lungs. All specimens were photographed, measured, and analyzed for color, consistency, dimensions, and lobar divisions, and subsequently preserved in 10% formalin. The results revealed that the three species maintain the same classic pulmonary anatomical pattern: the right lung is divided into cranial, middle, caudal, and accessory lobes, and the left lung is divided into a cranial lobe (with cranial and caudal portions) and a caudal lobe. However, significant proportional differences were observed between them, especially in tracheal length and lung lobe size. L. pardalis presented the largest dimensions, consistent with its larger body size; L. tigrinus exhibited proportionally wider lungs relative to its length; and F. catus presented intermediate values, proving useful as a comparative model, although it does not fully replace specific analyses in wild felines. The study concludes that, despite the structural similarities, the proportional differences highlight ecological adaptations and reinforce the importance of comparative anatomical research for veterinary management, conservation, and clinical practice.
