Two Sumatran tiger cubs were born August 5 at the Smithsonian National Zoo in Washington, D.C.

Here's a peek at the double cuties in action:


The cubs' arrival was heralded on the zoo's Twitter account Thursday morning:


The birth is especially good news because Sumatran tigers are critically endangered; fewer than 400 now exist, according to the World Wildlife Fund.

This is mom Damai's first litter of cubs, says the zoo, although she and 12-year-old male tiger Kavi have "bred several times from December 2012 through mid-April of 2013."

On Tuesday, Damai left her little ones to eat, which the zoo noted "is a good sign! It means she feels comfortable."

The yet-unamed cubs won't go on exhibit until late autumn but cub watchers can follow their activity via a live tiger cub cam.

One thing's for sure: they certainly give the National Zoo's 11-week-old fishing cat Wasabi a run for his money in the purr-fectly adorable kitties department!
