The Smithsonian National Zoo's family of Asian small-clawed otters—the smallest, cutest otter species in the world—spent some time over the weekend with one of their favorite toys: a keyboard to bang on. With their small claws, natch.

This is an exercise in animal enrichment—something the zoo says ranks with nutrition and medicine in terms of an animal's quality of life—but it's just as much fun for humans as it is for otters.

The small-claws get keyboard practice sessions twice a month, to "engage their sight, touch, and hearing senses."
