All cats are not created equal. While Cyrus was a quiet cat, the dignified, strong and silent type, Musetta is a little loudmouth. In fact, since we were just away for a week, she's been quite chatty. Some would say demanding. And last night, I realized something. More than the barristas at the local 1369 and Peet's coffeehouses, Musetta is the model for my spunky punk rocker Violet. ("Thank God she can't dye her hair purple," says my husband.) After all, my heroine, Theda, is often prompted into action by those early morning calls... sound familiar?
