Zookeepers in Russia say they've found the culprit behind the giant snowballs discovered in a Siberian tiger's enclosure.
It turns out the tiger did it! Officials at the Kaliningrad Zoo say they were concerned about someone throwing the snowballs at the animal. But a camera eventually caught the big cat rolling the snow herself.
Zookeepers say the tiger makes the balls at night and then entertains visitors by pushing them around during the day.
