In the video, a person is seen using a small cup to train a rat. The rat is black and white and is standing on a brown mat. The person is holding the cup in their hand and moving it around to encourage the rat to move. The rat follows the cup around and eventually drinks from it. The person then rewards the rat with a treat. The video shows the person repeating this process several times, with the rat following the cup and drinking from it each time. The video is shot in a room with a grey wall in the background.
