This cute YouTube video will melt your heart. It comes from the zookeepers at Woodland Park Zoo in Seattle, Washington. And it features two wide-eyed Ocelot kittens.

Ocelots are on the endangered species list. Fur traders once valued them for their unique pelts. They used to live throughout the American southwest. Now, fewer than an estimated 100 live in Texas.

The Woodland Park Zoo plays a key role in building up the ocelot population. Since 1973, more than 20 ocelots have been born there. These two are the latest additions.
