CC, for "CopyCat" or "Carbon Copy" (December 22, 2001 – March 3, 2020), was a brown tabby and white domestic shorthair and the first cloned pet. She was cloned by scientists at Texas A&M University in conjunction with Genetic Savings & Clone Inc.
CC's surrogate mother was a tabby, but her genetic donor, Rainbow, was a calico domestic longhair. The difference in hair coloration between CC and Rainbow is due to X-inactivation and epigenetic re-programming, which normally occurs in a fertilized embryo before implantation.
On March 3, 2020, CC died at 18 years old in College Station, Texas.
