Abstract A 7‐year‐old spayed female domestic shorthair cat was presented with respiratory distress due to presumed spontaneous pneumothorax. High‐resolution computed tomography identified subpleural blebs and paraseptal emphysema with peribronchial thickening and bronchiectasis. Feline lower airway disease was suspected as the underlying cause, considering the patient's chronic exposure to environmental tobacco smoke within the household and computed tomography findings. The pneumothorax persisted despite medical treatment and continuous suction via thoracostomy tube. Allogenic blood patch pleurodesis was performed twice, leading to resolution of the pneumothorax. Recurrence after 5 months resolved with thoracocentesis alone.
