Baba Ganoush stares at her reflection in a mirror as her sibling Tabouli crouches below her, Thursday, Aug. 5, 2004, in San Francisco. These two kittens are the first cats cloned by chromatin transfer, a new cloning technology developed by Genetic Savings & Clone, a pet gene banking and cloning company, who produced the kittens as a precursor to production of the first batch of cat clones for the public. It will cost $50,000 to have your cat cloned. (AP Photo/Ben Margot)
