In the video, a young boy is seen holding a small grey rodent in his hands. He then places the rodent on a blue plastic cage and opens the door of the cage. The rodent quickly runs inside the cage and the boy closes the door. The boy then picks up the rodent again and places it back on the cage. The rodent runs inside the cage again and the boy closes the door. The video is a simple demonstration of the boy playing with the rodent and showing how it can run in and out of the cage.
