John Lennon's mother, Julia, had a cat named Elvis (after Elvis Presley), which fostered John's own fascination with felines. Growing up in Liverpool, the Beatle-to-be had three cats: Tich, Tim, and Sam. With wife Cynthia, he had a tabby named Mimi. With May Pang, he had a white cat and a black cat -- Major and Minor. John and Yoko Ono shared their New York home with another black and white pair -- Salt and Pepper. You can check out his sketches of his cats at play in the books A Spaniard in the Works and Real Love: The Drawings for Sean.
