Colorado’s wildlife history books have been rewritten with the discovery of 10 tiny lynx kittens! Researchers in the state were thrilled to discover the endangered babies – seven female, three male – in mountain dens in May, the first documented in Colorado since 2006.

“The discovery of kittens this year is extremely promising,” said Tanya Shenk, a Colorado Division of Wildlife lynx field researcher, in a statement. “The locations of the dens show that lynx are beginning to expand their ranges and are once again finding both food and habitat necessary for successful reproduction.”

According to the Associated Press, the felines were native to Colorado before being wiped out by logging, trapping, poisoning and development in the 1970s. Since the state’s lynx reintroduction program began in 1999, a total of 218 lynx have settled there after being brought in from Alaska and Canada.

We hope these little kitties make themselves at home and stay a while!
