A rare leopard cub has been born in a zoo in a “huge milestone” for the critically endangered species.

Bosses at Dartmoor Zoo in Devon announced the successful birth of the Amur leopard cub to parents Lena and Freddo.

The species is described as the “world’s rarest big cat” with only an estimated 120 remaining in the wild, and staff said zoological records showed only 15 Amur leopards had been born in captivity worldwide this year.

The unnamed cub at Dartmoor was born on 29 September, with its birth captured on CCTV, but the arrival was only announced by the zoo this week.
