The National Zoo in the U.S. is celebrating the birth of a pair ofSumatran tiger cubs, a critically endangered species.
The zoo announced Thursday that the cubs born to 4-year-old Damai on Monday appear to be healthy, and the new mother has been seen grooming and nursing them.
This is Damai's first litter, sired by 12-year-old Kavi. The zoo confirmed Damai's pregnancy in June through an ultrasound after she gained weight and exhibited behaviors indicating she could be pregnant.
Damai is being remotely monitored to allow her to bond with her cubs. The cubs won't be exhibited for several months, but fans can watch them on webcams.
