The Pittsburgh Zoo & PPG Aquarium announced Tuesday that a rare Amur leopard cub was born on Feb. 4. It will be six weeks before the cub’s sex will be determined and three months before it will be ready to leave the den. Its mother, 12-year-old “Candy,” had a series of miscarriages and a stillbirth in the past, and the zoo claims she is the oldest first-time mom of her kind in North America.

“The birth of our Amur leopard Candy’s first cub is important because it is the first introduction of Candy’s bloodline into the North American Amur leopard population,” Barbara Baker, President and CEO of the Pittsburgh Zoo & PPG Aquarium, said in a statement.

Amur leopards are described as “extremely endangered.” There may only be 60-70 of these animals left in the wild and about 220 in zoos around North America, Europe, and Japan.
