One of two rare Indian lion cubs born on New Year's Day at Zurich zoo has been eaten by its parents, the Swiss news agency reported Tuesday. It quoted a big cat specialist at the zoo as saying that the lions probably considered the cub too weak to survive and ate it to help the chances of the other cub, which is doing well. Less than 200 Indian lions remain in the wild and the species is considered to be threatened with extinction. The cubs' mother, known as Mena, gave birth to two other cubs in 1993. Both survived and now are in a zoo in Berlin. The birth of the two cubs Monday was followed by visitors to the zoo via an infrared camera linkup. Mena and her mate, Bagirath, were given to Switzerland by India in 1991 to mark the 700th anniversary of the founding of the Swiss federation.
