Cheetah girls? Nope, cheetah boys.

In its first #CheetahCubdate released Friday, the Smithsonian National Zoo confirmed the two cubs to which four year-old Amani gave birth earlier this month are male.

At just under two weeks old, the cubs are reportedly doing well and cheetah keepers say both they, and mom Amani are showing normal, healthy, cheetah behavior. The cubs are said to be nursing regularly and gaining weight, with each clocking in at around 2.5 pounds at their most recent weigh-in.

At night, all three of the cheetahs sleep together in a cuddle puddle which is apparently just as important to their survival as it is nauseatingly cute, since the cubs are so young they cannot regulate their own body temperatures yet.

Zookeepers describe the cubs as “feisty,” and are not shy about hissing when an official enters the exhibit. Their eyes are fully open and they are just starting to realize how much control they have over their legs. So, while the cubs are a little shaky now, there is little doubt that they will be tumbling around the enclosure in no time.

Amani, zookeepers say, is being a “wonderful first-time mom.” She is said to be keeping up with her nourishing diet, nursing the cubs regularly, and giving the kids some healthy distance by periodically leaving them to eat or patrol her enclosure. When she is with the cubs, zookeepers say you can often see her grooming them and can hear her purr loudly as she does so.

The cubs were born at the Smithsonian Conservation Biology Institute in Front Royal, Virginia, which is around 70 miles outside of the city. The location is not open to the public, save for one day each year in the fall, which fell on Oct. 2, ironically the day before the cubs were born.

The National Zoo and Conservation Biology Institute is one of ten institutions in the U.S. involved in the Cheetah Breeding Center Coalition; it calls the birth of these cubs a “significant addition to the Cheetah Species Survival Plan.17 litters of cubs have been born at the Front Royal campus over the past 15 years.
