4-year-old DSH Feline presented for anorexia. The clinical exam revealed a 4/6 systolic heart murmur. An echocardiogram was performed discovering Tetrology of Fallot; pulmonic stenosis, ventricular septal defect, right ventricular hypertrophy, overriding aorta. Unfortunately further analysis revealed Feline Infectious Peritonitis and the patient was eventually euthanized.
