In the video, a small hamster is seen running inside a wheel. The wheel is black and appears to be made of plastic. The hamster is brown and white in color and is running at a fast pace. The wheel is located inside a cage, which has a blue base and white bars. The hamster's fur is fluffy and it has small, round eyes. The wheel is spinning quickly, and the hamster seems to be enjoying the exercise. The background is blurred, but it appears to be a room with a window.
