America is cat crazy, and Mark Twain may have been the American writer most crazy about cats. From his boyhood in Hannibal, Missouri, to his last years in Connecticut, Mark Twain spent much of his life surrounded by cats, and they stalk through many of his best-known books, including The Innocents Aboard, Roughing It, The Adventures of Tom Sawyer, A Connecticut Yankee in King Arthur's Court, and Puddn'head Wilson. In this lighthearted book, Twain scholar Mark Dawidziak explores the writer's lifelong devotion to cats through stories, excerpts, quotes, photos, and illustrations, illuminating a little-known side of this famous writer's life that will appeal to Twain aficionados and cat lovers alike.
