Like pet rats, pet mice should not be left unsupervised outside as they have many natural predators, including (but not limited to) birds, snakes, lizards, cats, and dogs. Male mice tend to have a stronger odor than the females. However, mice are careful groomers and as pets they never need bathing. Well looked-after mice can make ideal pets.
Mice are good jumpers, climbers, and swimmers, and are generally considered to be thigmotactic, i.e. usually attempt to maintain contact with vertical surfaces. [citation needed] Mice are mostly crepuscular or nocturnal; they are averse to bright lights. The average sleep time of a captive house mouse is reported to be 12.5 hours per day.
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus Rattus. Other rat genera include Neotoma (pack rats), Bandicota (bandicoot rats) and Dipodomys (kangaroo rats). Rats are typically distinguished from mice by their size.
Genetic variation, such as better peripheral vision, can make some rats “bright” and others “dull”, but does not determine their intelligence. [3] Nonetheless, Tryon’s famous rat-maze experiment demonstrated that the difference between rat performances was genetic since their environments were controlled and identical. [4]

Laboratory rats or lab rats are strains of the rat subspecies Rattus norvegicus domestica (Domestic Norwegian rat) which are bred and kept for scientific research. While less commonly used for research than laboratory mice , rats have served as an important animal model for research in psychology and biomedical science [ 1 ] , and "lab rat" is ...
A print showing cats and mice from a 1501 German edition of Aesop's fables Murids feature in literature, including folk tales and fairy stories. In the Pied Piper of Hamelin , retold in many versions since the 14th century, including one by the Brothers Grimm , a rat-catcher lures the town's rats into the river, but the mayor refuses to pay him.
Included are mice, rats, gerbils, hamsters, lemmings, and voles. They are grouped according to the structure of their jaws and molar teeth . They are characterized by their myomorphous zygomasseteric system , which means that both their medial and lateral masseter muscles are displaced forward, making them adept at gnawing.
