The video shows a guinea pig with a brown and black coat walking around in a pen with hay on the ground. The guinea pig is seen sniffing the ground and moving around the pen. There are other guinea pigs in the background, but the focus is on the one with the brown and black coat. The pen appears to be indoors, and there are no visible toys or food for the guinea pigs. The lighting is dim, and the video quality is not very clear.
