JACKSONVILLE, Fla. -

The Jacksonville Zoo and Gardens is welcoming two endangered Amur leopard cubs.

The infant females were born Nov. 16 and given their first checkup by zoo staff on Tuesday. They were each 4 pounds.

Zoo officials say this is the third litter for the parents, Makarii and Nicolai, since they arrived at the zoo in 2006. Makarii gave birth to one cub in 2011 and two in 2012.

Amur leopards are native to southeast Russia and northeast China. Experts believe fewer than 50 remain in the wild, and about 95 live in captivity in the United States.
