Tracheal obstruction caused by tree needles in a cat

Tracheal obstruction was suspected in a 1-year-old female domestic shorthair cat. Clinical signs consisted of inspiratory and expiratory dyspnea and cyanosis. The cat did not improve when treated with oxygen, epinephrine, prednisolone sodium succinate, and aminophylline. Bronchoscopy revealed obstruction of the trachea and carina by a 2.5-cm twig and needles from a Douglas fir tree. Needles had migrated into distal airways. The cat was euthanatized at the owner's request.
