The video shows a small brown mouse running around in a cage. The cage is filled with hay and has a blue plastic bowl in the center. The mouse runs towards the bowl, climbs on top of it, and then jumps off. The mouse then runs around the cage, exploring its surroundings. The video is shot from a top-down perspective, allowing the viewer to see the mouse's movements clearly. The mouse's fur is a mix of brown and white, and it has a small, pointed nose. The blue bowl is empty and has a few small holes in the bottom. The hay is a light yellow color and is scattered all over the cage floor.
