The Prague Zoo says five cheetah cubs that were recently born in the park are doing well.

The zoo said Thursday the quintuplets — three male and two female — have survived the most critical period after their May 15 birth and that their mother, 6-year-old Savannah, is taking good care of them.

Cheetahs are the fastest animals on land but also are vulnerable to diseases. Scientists say every cub is critical to saving the species, which is threatened with extinction in the wild.

It was the second birth for Savannah, who gave birth to quadruplets in 2014. In both cases, five-year-old Ben was the father. The cubs have not yet been named.

Visitors will have the first chance to see them on Aug. 26.
