Aren't tuxedo cats just something else!!! We have Tina Peepers, and like Butter, she is a real sweetie. To Butter's parent: our Riley was diagnosised at 8 months with cardiac disease(left ventricular hypertrophy). He is still a rascal at 7+ years, no symptoms, nor meds!! Hoping Butter turns out the same way. HAPPY COTD!!!!!
