The common mouse is a small rodent found all across the globe. Their tails and round ears have no fur, and their body fur can be in a variety of colors - white, black, grey, and/or brown & red, possibly with spots. Mice are generally nocturnal so they are most active at night, and are scavenging omnivores that tend to eat insects, seeds, and plants. Some general predators for mice are birds of prey (hawks, owls, etc) snakes, and mammals like foxes and cats. Laboratory mice are bred and often used for scientific research, and have led to great advancements in genetics, medicine, psychology, and more!
