Signalment:10-year-old, female spayed Domestic Shorthair cat

History:The cat acutely vocalized, vomited, and began dragging his hind legs. The owner reported that the cat was making a “gurgling” noise in the car. The cat presented for euthanasia laterally recumbent with a gallop rhythm on auscultation. The cat went into respiratory arrest and was euthanized.

Gross Lesions:The heart was diffusely and moderately enlarged. The left ventricular free wall myocardium was thickened, and the left ventricular lumen was narrowed. Three thrombi were identified within the lumen of the abdominal aorta. The cranial most thrombus measured 3x0.5x0.4 cm and was directly caudal to the diaphragm. The next was 4.5 cm caudal to the first thrombus, measured 5x3x3 mm, and extended 1 mm into the left renal artery. The most distal thrombus measured 7x4x3 mm and was 4 cm caudal to the second thrombus, adjacent to the iliac arteries.
