In February 2004, Genetic Savings and Clone, a private company that provided tissue-banking services of beloved animals to pet owners along with conducting cloning research, offered its clients the opportunity to clone their favorite cat for $50,000 per animal. Four tissue donors signed up for the service. Two years earlier, the company announced that it had successfully cloned a cat, named CC (for Carbon Copy or Copy Cat). The research has been funded by a wealthy financier who believes that cloning pets will be a successful business in the future.

In August 2005, Korean scientists created the first dog clone, an Afghan hound named Snuppy. The scientists reported that their motive for performing the experiment was creating dogs for research in human diseases. Groups like the American Kennel Club expressed concerns about the ethics of the practice and its potential long-range impact on dog breeding.
