One of the cubs is a male and one is a female. The male cub weighs a little more than eight pounds, and the female was seven and a half pounds.
During the exam, the cubs received transponder microchips, and veterinarians collected blood and fecal samples from them.
Tiger Damai gave birth to the cubs on August 5 and has been caring for them since. The cubs will not be on exhibit for several months.
