A white mouse with a pink tail is in a clear plastic enclosure. The enclosure contains bedding made of wood shavings and crumbled paper. There is a small metal tag on the mouse's left ear. In the background, there is a food dish containing small brown pellets and what appears to be a piece of cardboard egg carton. The mouse is facing to the right and appears to be grooming itself. The enclosure is stacked with other similar enclosures.
