SAN FRANCISCO - The first cloned-to-order pet sold in the United States is named Little Nicky, a 9-week-old kitten delivered to a Texas woman saddened by the loss of a cat she had owned for 17 years.

The kitten cost its owner $50,000 and was created from DNA from her beloved cat, named Nicky, who died last year.

"He is identical. His personality is the same," the owner, Julie, told The Associated Press in a telephone interview. Although she agreed to be photographed with her cat, she asked that her last name and hometown not be disclosed because she said she fears being targeted by groups opposed to cloning.

Yet while Little Nicky, who was delivered two weeks ago, frolics in his new home, the kitten's creation and sale has reignited fierce ethical and scientific debate over cloning technology, which is rapidly advancing.
