A four-year-old spayed female domestic shorthair cat, weighing 4.0 kg, was presented for episodic shortness of breath. The cat was diagnosed with hypertrophic cardiomyopathy based on the results of physical, electrocardiographic, radiographic and echocardiographic examinations. A large free-floating ball thrombus was also detected in the left atrium on echocardiography. Although medical therapy for heart failure was initiated, the cat died of acute pulmonary edema 36 days after presentation.
