In the video, there are several guinea pigs of different colors and sizes. They are seen eating green leaves that are placed in front of them. The guinea pigs are standing on a bed of wood shavings, and they are all focused on eating the leaves. The leaves are long and narrow, and the guinea pigs are using their mouths to pull the leaves and eat them. The colors of the guinea pigs range from black, brown, to white and orange. The video captures the guinea pigs in a close-up shot, allowing us to see their fur texture and the way they eat.
