Are you a cat person, or would you like to be one? Welcome to the club. Thirty-four percent of American households include at least one cat, which adds up to 90 million pet kitties owned in the U.S. If you're thinking about getting a cat — or want to know more about the one you've got — the new book The Cat Bible: Everything Your Cat Expects You to Know (Gotham) is an excellent place to start. Author Tracie Hotchner is one of the leading experts of the feline world. Her popular radio show, Cat Chat, which airs Wednesdays on Sirius radio, celebrates its first anniversary in November. TIME's Andrea Sachs (who has two cats herself) caught up with Hotchner between broadcasts in Vermont.
