It’s difficult to write nonfiction that is so engrossing and relatable that it reads like fiction, yet that is just what veterinarian Dr. Amy Attas manages to do in her book “Pets and the City: True Tales of a Manhattan House Call Veterinarian.” This collection of anecdotes and personal history ranges from the why—the reason Attas wanted to become a veterinarian and how she accomplished that—to the many famous people who were/are her clients. From Joan Rivers to Billy Joel, we read about the connections that the uber rich and famous have with their pets. But we also read about those not in that stratosphere of economic wealth, and how money doesn’t dictate how much we love our four-legged (and sometimes three-legged) pets.
