In the video, a small guinea pig is seen eating a piece of cucumber. The guinea pig is black and white in color, and it is being held by a person's hand. The cucumber is green and appears to be fresh. The guinea pig is nibbling on the cucumber, and its mouth is moving as it eats. The person's hand is steady, holding the cucumber in place for the guinea pig to eat. The background is not clearly visible, but it appears to be an indoor setting.
