Bangkok's zoo has unveiled new arrivals to its white Bengal tiger family — a pair of white-and-black striped cubs named "One" and "Two."The Dusit Zoo held a photo opportunity Thursday for the 50-day-old female cubs, who were born Nov. 16. Zookeeper Noppadon Tiptanya says it is the sixth time the cubs' 15-year-old mother has given birth in captivity at the zoo. Female white tigers generally produce a litter of between one and four cubs.

The zookeeper says the cubs are being fed on mother's milk to ensure their early upbringing is as natural as possible. The cubs will be presented to the public on Saturday, when Children's Day is celebrated in Thailand.
