The famous two-faced cat, Frank and Louie (sometimes called Frankenlouie), passed away this week at the ripe old age of 15. The Massachusetts feline held the Guinness Book of World Records title for the longest lived Janus cat.
Named for the Roman god Janus, who was usually portrayed as having two faces, domestic cats with two faces are extremely rare, noted Leslie Lyons of the University of Missouri's Department of Veterinary Medicine and Surgery, who specializes in feline genetics.
