Three lion cubs are inside an enclosure with a brown floor and brown wooden walls. Two cubs are lying together, one appearing to eat something, while a third cub lies apart from the others, also appearing to eat. Circular windows are set into the walls. A tree branch stands next to one of the windows. The walls are topped with a brown wooden roof. The room is illuminated by overhead lighting.
