In this Wednesday, Sept. 28, 2011 photo, a cat with two faces, named Frank and Louie, is walked by the cat's owner for the purpose of being photographed at their home in Worcester, Mass. The animal is known as a Janus cat, named for the figure in Roman mythology with two faces on one head. The owner, who identified herself only as Marty, calls the face on the left Frank, while the face on the right she identifies as Louie. (AP Photo/Steven Senne)
