A host of endangered species have been born recently at zoos and sanctuaries around the world. In a zoo in Poland, a Sumatran Tiger cub, born in May, romped with its mother. Two Asiatic Lion cubs were born at a zoo in Rome this spring. On the other end of the cat size spectrum, two Black Footed Cats were born in April at the San Diego Zoo. The Black Footed Cat is one of the smallest wild cat species in the world. It’s also one of the deadliest.
