Cute! World's rarest big cats born at Twycross Zoo

Staff at Twycross Zoo are celebrating the pitter-patter of little paws after the birth of two of the world's most endangered big cats, the Amur leopard.

With fewer than 50 of the cats left in the wild, the new arrivals form part of a conservation effort to save the species from extinction.

Amur leopards live in China and south-eastern Russia, where they face the threat of poaching, illegal logging, forest clearance and land development - on top of the risks posed by disease and in-breeding in such a small population.
