You may already know the jaguar is the largest cat native to the Americas, and the third largest cat in the world, behind lions and tigers. What you might not know until you watch this video is that jaguars also have possibly the cutest baby cubs in the world. When the video was shot this cub was just 4lbs and two weeks old. Born this past March at the San Diego Zoo, the unnamed cub runs around its pen and shows off its tiny fangs while mom Nindiri watches over play time. The only downside of this video is knowing you'll never get to play with this cub yourself. Get ready to go awwww.
