A '''mouse''' (plural '''mice''') is a [[rodent]] that belongs to one of numerous [[species (biology)|species]] of small [[mammal]]s. The best known mouse species is the [[mus musculus|common house mouse]] (''Mus musculus''). It is found in nearly all countries and, as the laboratory mouse, serves as an important [[model organism]] in biology; it is also a popular [[pet]]. The American [[white-footed mouse]] (''Peromyscus leucopus'') and the [[deer mouse]] (''[[Peromyscus maniculatus]]'') also sometimes live in houses. These species of mice live [[commensalism|commensally]] with humans. |
|||
Although they may live up to two years in the lab, the average mouse in the wild lives only about 3 months, primarily due to heavy [[predation]]. [[Cat]]s, wild [[dog]]s, [[fox|foxes]], [[bird of prey|birds of prey]], [[snake]]s and even certain kinds of [[insect]]s have been known to prey heavily upon mice. Nevertheless, due to its incredible adaptability to almost any environment, and its ability to live commensally with humans, the mouse is regarded to be the third most successful mammalian species living on Earth today, after humans and the [[rat]]. |
|||
Mice can be harmful [[Pest (organism)|pest]]s, damaging and eating [[Crop (agriculture)|crops]] and spreading [[disease]]s through their [[parasite]]s and [[feces]]. In the Western United States, breathing dust that has come in contact with mouse feces has been linked to the deadly [[hantavirus]]. The original motivation for the domestication of [[cat]]s is thought to have been for their predation of mice and their relatives, the [[rat]]s. |
|||
==Body and behavior== |
|||
Mice are small rodents, resembling diminutive rats. Usually they have pointed snouts and small ears. The body is typically elongated with slender, usually hairless tails, but different types of mice show large variations. Body dimensions vary considerably by species, though some approximate values are available: total length 28-130 mm, mass 2.5 to >34g<ref name = Novak> Nowak, Ronald M. 1999. Walker's Mammals of the World, 6th edition. Johns Hopkins University Press, 1936 pp. ISBN 0-8018-5789-9</ref> |
|||
Mice generally live on an [[herbivore]] diet, but are actually [[omnivore]]s; they will eat meat, the dead bodies of other mice, and have been observed to [[Self-cannibalism|self-cannibalise]] their tails during starvation. [[Grasshopper mouse|Grasshopper mice]] are an exception to the rule, being the only fully [[carnivore|carnivorous]] mice. Mice eat [[grain]]s, [[fruit]]s, and [[seed]]s for a regular diet, which is the main reason they damage crops. They are also known to eat their own [[feces]]. |
|||
Mice are [[social animal]]s. They prefer to live in groups. Male rivalry can become harmful for the animals, especially when a group is confined to a small space. The natural [[Habitat (ecology)|habitat]]s of the mouse are very diverse. Mice can be found in forests, savannahs, grasslands and rocky habitats <ref name = Novak/>. In Africa they tend to particularly like forest edge, derived savannah, and (as elsewhere) agricultural areas. Mice build nests for protection and warmth, but species differ in their preferences: ''M. minutoides'' nests in shallow burrows; ''M. caroli'' and ''M. cervicolor'' burrow; and ''M. shortridgei'' and ''M. pahari'' nest aboveground. Most species will construct nests of grass, fibers, and shredded material<ref name = Novak/>. Mice do hibernate. |
|||
The mouse has bichromatic vision, lacking a photopigment that can detect red light.<ref>Jacobs GH, Williams GA, Fenwick JA. Influence of cone pigment co-expression on spectral sensitivity and color vision in the mouse. Vision Res. 2004; 44(14):1615-22</ref> |
|||
==Taxonomy of the genus ''Mus''== |
|||
The term "mouse" in common usage is roughly equivalent to the taxonomic term ''Mus'', while house mouse is equivalent to ''Mus musculus''. In common language the term "mouse" often refers incorrectly to ''Mus musculus''. |
|||
However, there are 38 [[species]] of mice (in the genus ''Mus''); see table below. |

==Laboratory mice== |
|||
Mice are the most commonly utilized animal research model with hundreds of established inbred, outbred, and transgenic strains. In the United States, they are not covered under the [[Animal Welfare Act]] (AWA) (administered by the [[United States Department of Agriculture|USDA]], [[APHIS]]) as an animal. However, the [[Public Health Service Act]] (PHS) as administered by the [[National Institutes of Health]] (NIH) does cover their humane treatment. |
|||
Mice are common [[experiment]]al animals in [[biology]] and [[psychology]] primarily because they are mammals, and thus share a high degree of [[homology (biology)|homology]] with humans. The mouse genome has been sequenced, and virtually all mouse genes have human homologs. They can also be manipulated in ways that would be considered unethical to do with humans. Mice are a primary mammalian [[model organism]], as are [[rat]]s. |
|||
There are many additional benefits of mice in laboratory research. Mice are small, inexpensive, easily maintained, and can reproduce quickly. Several generations of mice can be observed in a relatively short period of time. Mice are generally very docile if raised from birth and given sufficient human contact. However, certain strains have been known to be quite temperamental. |
|||
==History== |
|||
Mouse-like species are among the oldest mammals. It has been proposed that higher mammals evolved from rodent-like species many million years ago. |
|||
Mice have been known to humans since antiquity. The Romans differentiated poorly between mice and rats, calling rats ''Mus Maximus'' (big mouse) and referring to mice as ''Mus Minimus'' (little mouse). In Spanish similar term are in use: ''ratón'' for mouse and ''rata'' for rat.[http://www.iberianature.com/trivia/etymology_mammals.htm] |
|||
Discoloration in mice was supposedly first noticed in China by 1100 BC, where a white mouse was discovered. However, there is sufficient evidence to believe that white mice were first noticed before that, in the times of the [[Greeks]] and [[Ancient Rome]]. |
|||
The word "mouse" and the word muscle are related. Muscle stems from ''musculus'' meaning small mouse - possibly because of a similarity in shape.[http://www.etymonline.com/index.php?term=mouse][http://www.etymonline.com/index.php?term=muscle] The word "mouse" is a cognate of [[Sanskrit]] ''mush'' meaning 'to steal,' which is also cognate with ''mys'' in [[Old Greek]] and ''mus'' in [[Latin]].[http://www.worldscibooks.com/lifesci/etextbook/p393/p393_chap1.pdf] |
|||
==Mice as food== |
|||
Humans have eaten mice since prehistoric times. They are still eaten as a delicacy throughout eastern [[Zambia]] and northern [[Malawi]], where they are an important source of [[protein]].[http://www.bridgewater.edu/~mtembo/mbeba.html] |
|||
===Mice as feeder animals=== |
|||
[[Image:Feeder_mice.jpg|150px|thumb|"Pinkie" mice for sale as reptile food.]] |
|||
A common use of mice is to feed many species of [[snakes]], [[lizards]], [[tarantulas]], and [[bird of prey|birds of prey]]. Most US pet stores now carry mice for this purpose. Because they breed quickly, grow quickly, are easy to care for, they can be sold in a wide variety of sizes. This makes them suitable for consumption by animals of many different sizes. Mice also seem to be a desirable food item for a very large variety of [[carnivores]]. Common terms used to refer to different age/size mice are pinkies, fuzzies, hoppers, and adults. Pinkies are newborn mice that have not yet grown fur. Fuzzies have some fur but are generally not very mobile, hoppers have a full coat of hair and are fully mobile but are smaller than adult mice. These terms also refer to the various growth stages of [[rat]]s (also see [[Fancy rat]]). |
|||
Mice specifically bred for pets and feeders are sometimes called [[Fancy mouse|fancy mice]]. |

|||
Mice are now one of the leading [[rodent]] pets. Although their main purpose in pet stores is to be sold as [[snake]] food, many people buy mice as companion pets. Some common mouse care products are: |
|||
*[[mouse cage|Cage]]- Usually a hamster or gerbil cage, but special mouse cages are now available. You can also use a small aquarium (5 gallons for up to 3 mice, 10 gallons for 8 or so mice) with a mesh top, so there is no risk of them escaping. |
|||
*[[mouse food|Food]]- Special pelleted and seed-based food is available. Mice can generally eat most rodent food (for rats, mice, hamsters, gerbils, etc) |
|||
*[[Pet bedding|Bedding]]- Usually hardwoods, such as aspen, though shredded, uninked paper or recycled virgin wood pulp can also be used. Cedar or pine should not be used because they contain harmful liquids that can damage any rodent's respiratory system. Corn cob bedding should also not be used because it promotes ''Aspergillis'' fungus and can grow mold once it gets wet. It also is quite rough on their feet. Whatever the bedding material, there should be at least 2 inches for digging and burrowing purposes. |
|||
Some benefits of having mice as pets are |
|||
*Minimal shedding and allergens |
|||
*Entertaining and affectionate |
|||
*Inexpensive |
|||
*Clean (contrary to popular belief) |
|||
*Socially self-sufficient (when in a group of other mice) |
|||
*Significantly less likely to bite than other rodent pets |
|||
*Mice are quite intelligent given their size |
|||
There are, however, some disadvantages to having pet mice |
|||
*Small and quite fragile (not as easy to handle as a dog or a cat) |
|||
*Nocturnal |
|||
*Frequent eye infections under stress |
|||
*Easily subject to disease when without optimal care |
|||
*Frequent reproduction |
|||
*Short lifespan |
|||
*Prone to many other diseases |
