LOUISVILLE, Ky. (WDRB) -- Move over Mozart and forget the piano-playing cat. There's a new musical mammal taking the Internet by storm.
Asian small-clawed otters are playing the keyboard.
If you watch the video above closely, you can even hear them "singing along."
It's all part of an animal enrichment program at the Smithsonian's National Zoo. Every few weeks, keepers set the keyboard up just outside the otter enclosure and it becomes a concert hall.
The otters' keyboard has to stay outside the enclosure so they don't rip it apart or sink it in their pool.
