Two critically endangered baby leopards were spotted nuzzling up to their mother moments after they were born at a U.K. zoo.
The Amur leopard cubs' mom, Kristen, could be seen in her birthing den earlier this week via livestream delivering her cubs unassisted at the Twycross Zoo in London.
Moments later, the mother leopard could be seen leading her babies to nurse for the first time.
The cubs, whose names and genders have not yet been released, are the second pair born to Amur leopards Kristen and Davidoff. Their first two were born in 2014.
"The mom and cubs are doing very well," a representative from the Twycross Zoo told InsideEdition.com. "Some visitors have already seen them poking out of the birthing den, but they haven't fully left yet."
According to a press release, Amur leopards are considered the rarest breed of large cats, and the birth of the two cubs is giving hope to researchers that the critically endangered species will be saved from the brink of extinction.
Experts believe there are less than 70 Amur leopards in the wild, and only 200 in zoos across the world.
