The video shows a group of baby mice in a nest. The mice are mostly naked, with only a few patches of fur. They are seen nursing from their mother, who is also in the nest. The mice are moving around and climbing over each other. The nest is made of straw and is located in a dark, enclosed space. The mice are mostly light brown in color, with some darker spots. The mother mouse is larger than the babies and has more fur. The video is shot from above, looking down on the nest.
