A common domestic cat served as a surrogate mother to give birth to a wildcat in a technique that researchers say can help save endangered species.

The embryo of an endangered Indian desert cat was implanted into the house cat by in-vitro fertilization, Cincinnati Zoo officials said Wednesday. The offspring was born Feb. 7."There are millions of domestic cats, and so few of these exotic cats," said Betsy Dresser, research director at the zoo's Center for Reproduction of Endangered Wildlife.

Zoo officials said they believed it was the first time a common domestic cat was used as the surrogate mother.
