The enclosure is filled with white gravel, and there is a small yellow toy inside. The person places the wheel into the enclosure, and the hamster begins to run on it. The wheel is then removed from the enclosure, and the hamster continues to run on it. The video shows the hamster running on the wheel from different angles.
