Lissa Warren’s father needed a retirement companion while his wife and daughter were at work. Enter Ting, a seven-pound Korat who changed his life, and the life of the family. All kittens are mischievous, but Ting “the cat grenade” was real trouble. She was also smart, endearing, and the soul of the Warren family.   In late 2008, Lissa’s father died of a heart attack. The images from that night still haunt her—especially the EKG readout ending in one long, devastating em dash. Less than a year later, Lissa and her mother stared at another EKG readout, this time for Ting. A living feline extension of the man they missed so much—the man they had tried, but failed, to save—she was diagnosed with a potentially fatal heart condition. The only option was to have a human pacemaker implanted in the cat—a procedure even the best animal hospital in Boston hadn’t performed in a decade. Thus they began a medical odyssey on behalf of the little gray cat who had been her father’s shadow—a journey that would prepare one of them for her own serious diagnosis.   A gorgeously written memoir about grief, hope, and how pets both complicate and enrich our lives, The Good Luck Cat is a testament to the power of the human—and the feline—spirit.
