The video shows a group of guinea pigs in a cage. The guinea pigs are of different colors and sizes, and they are moving around the cage. Some of them are climbing on top of a wooden house, while others are running around the cage. The cage is filled with hay, and there are several wooden houses and tunnels for the guinea pigs to explore. The lighting in the video is dim, and the camera is shaky, making it difficult to see the details of the guinea pigs.
