Rare twin leopard cubs born at San Diego Zoo
The San Diego Zoo is celebrating the birth of twin Amur leopards, one of the world’s most endangered species. The zoo says fewer than 300 of the big cats are estimated to exist on earth. The twins were born several weeks ago and have just emerged from their birthing den with their mother, Satka. Zoo officials say the time in the den allowed the cubs to bond with their mother. They say both appear to be healthy. The cubs have not yet been named and zookeepers won’t know the sex of the twins until they get a full veterinary exam.
