The video shows a small rodent, possibly a hamster, inside a cage with a yellow wheel. The rodent is seen running on the wheel, and then it stops and climbs out of the wheel. The cage appears to be made of metal bars, and the wheel is attached to the side of the cage. The rodent has a white and grey fur coat, and its movements are quick and agile. The video captures the rodent's playful and active nature as it explores its environment.
