In the video, we see a group of guinea pigs in a pen. The pen is filled with hay, and there are several objects in the pen, including a green pot with a plant in it, a red brick, and a piece of lettuce. The guinea pigs are of different colors, including black, white, and brown. They are moving around the pen, sniffing and nibbling on the lettuce. The camera is focused on the guinea pigs, and we can see them from different angles as they move around the pen. The lighting in the video is natural, and the guinea pigs appear to be healthy and active.
