Adorable footage of two new-born Amur Leopard cubs coming out of their den at Twycross Zoo in Atherstone, UK earlier today.

The big cat species is listed as critically endangered so these cubs, the second litter born to their mum Kristen and dad Davidoff, are a big deal for the zoo.

"After waiting for hours for mum to bring out her two cute Amur Leopard cubs from the den ... they finally made my day," the filmer later wrote online.

"Nothing at first as it started to rain, but as soon as the sun came out, so did the cubs."

"Those babies are something to be proud of for everybody involved with only a few left in the wild and classified as Critically Endangered," she continued.

After waiting for hours for mum to bring out her two cute Amur Leopard cubs from the den at the Twycross Zoo in Atherstone, England they finally made my day. Nothing at first as it started to rain, but as soon as the sun came out, so did the cubs. Mum Kristen never far away. These cubs were ready to play with their gorgeous tinged blue eyes, healthy looking, those babies are something to be proud of for everybody involved with only a few left in the wild and classified as Critically Endangered. This is the second litter for mum Kristen and dad Davidoff. The cubs haven't been named yet.
Sorry about the shaky video. I couldn't keep still as the people behind me keep pushing me. Everybody wants to see those two cubs. :-)
