The brother and sister were orphaned in Oregon last August when they were only a few weeks old.
Without a mother, they never learned how to live in the wild. They've been at the zoo for more than a month and will go on display soon.
For now, they're being trained by zookeepers as their exhibit space is made ready for public viewing.
Correction: The cubs are at the Orange County Zoo. It was earlier reported that they're at the Santa Ana Zoo.
