Amur leopards are perfect hunters.

An excerpt from the article 22 facts about Amur leopard
Although they would feed on hares, badgers, or mice, they prefer larger prey, even three times their size. They hunt for boars and deer, silently sneaking up on them, and attacking at the perfect moment. Their most preferred are the Siberian roe deer, Siberian musk deer, Manchurian sika deer, Manchurian wapiti, and even Amur moose (Amur elk), which are considered the world’s largest deer.
