Adorable footage of two new-born Amur Leopard cubs coming out of their den at Twycross Zoo in Atherstone, UK earlier today. <br /><br />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. <br /><br />"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. <br /><br />"Nothing at first as it started to rain, but as soon as the sun came out, so did the cubs." <br /><br />"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.
