Like most kittens, Duo loves to play, chow down and scamper around the house. Unlike most kittens, Duo happens to have two faces. The kitten was born with a rare condition called diprosopus, or craniofacial duplication, which means she has one head, two mouths, two noses and four eyes. California veterinarian Dr. Ralph Tran adopted Duo and is amazed at the progress she has made. "She loves life, she loves to play, she takes whatever is thrown at her and makes the best of it," Tran said.
