The word "mouse" and the word muscle are related. Muscle stems from musculus meaning small mouse - possibly because of a similarity in shape. The word "mouse" is a cognate of Sanskrit mus meaning 'to steal,' which is also cognate with mys in Old Greek and mus in Latin.
The Mice are small animals that belongs to one of numerous species of rodents. The best known Mouse species is Mus musculus aka the common house mouse. It is found in almost every country there is. It is also a popular pet, some species of mice live commensally with humans. Laboratary tests or biology studies also often use the Mus musculus.
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 terms are in use: ratón for mouse and rata for rat.

Mice and their relatives the rats, can be harmful pests, damaging and eating crops and spreading diseases through their parasites and feces.

Mice are common experimental animals in biology and psychology primarily because they are mammals, and so share a high degree of homology with humans. They are the most commonly used mammalian model organism, more common than rats. 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 by Animal Rights modern standards.

There are other reasons for why mice is used 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. Mice (and rats) have the same organs in the same places, just different proportions.
There are hundreds of established inbred, outbred, and transgenic strains.

Humans have eaten mice since prehistoric times. They are still eaten as a delicacy throughout eastern Zambia and northern Malawi, where they are an excellent seasonal source of protein. In most other countries, mice are no longer routinely consumed by humans. Some people are very afraid of mice, which is normal. Across the US petowners keep exotic pets such as snakes, lizards, frogs, tarantulas, and birds of prey. Most US pet stores now carry mice for this purpose. Because they breed quickly, grow quickly, are easy to care for, and can be sold in a wide variety of sizes, this makes them suitable for consumption by animals of various 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 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 rats (also see Fancy rat).

Mice should not be left outside as there have many predators such as birds. Watch them at all times when outside. Mice are partially smelly, more so the males than females, so it would be wiser to buy a female when choosing, although more expensive at times. If you look after your pet carefully and well you'll have the perfect pet.

A mouse in the wild lives, if lucky, up to 5 months, primarily due to heavy predation. Cats, wild dogs, foxes, birds of prey, snakes and even certain kinds of insects have been known to prey heavily upon mice. Due to its remarkable adaptability to any environment, the mouse is the third most successful mammalian species living on Earth today, after humans and the rat.
Mice range in size from 3 to 14 inches (8 to 35 cm) long (including a long tail). They weigh from 1/4 to 2 ounces (7 to 57 gm). The coat color ranges from white to brown to gray. Most mice have a pointed snout with long whiskers, round ears, and thin tails. Many mice scurry along the ground, but some can hop or jump.

All species of Mus are native to Eurasia and Africa, where they range from lowlands to mountaintops. The five species in the subgenus Pyromys are found in Sri Lanka, India, and mainland Southeast Asia. Much of their range originally consisted of open grasslands or grassy patches in forests.

The mouse is an omnivore; it will eat almost anything. It eats grain, seeds, grasses, fruit, roots, stems, and small animals like worms, grasshoppers (and other insects), arachnids, etc.
Mice are timid, social, and territorial. They are usually active in the night time, while others, such as the harvest mouse, are active both day and night.

Breeding onset is at about 50 days of age in both females and males, although females may have their first estrus at 25-40 days. Mice are polyestrous and breed year round; ovulation is spontaneous. The duration of the estrous cycle is 4-5 days and estrus itself lasts about 12 hours, occurring in the evening. Vaginal smears are useful in timed matings to determine the stage of the estrous cycle. Mating is usually nocturnal and may be confirmed by the presence of a copulatory plug in the vagina up to 24 hours post-copulation. The presence of sperm on a vaginal smear is also a reliable indicator of mating.
Female mice housed together tend to go into anestrus and do not cycle. If exposed to a male mouse or the pheromones of a male mouse, most of the females will go into estrus in about 72 hours. This synchronization of the estrous cycle is known as the Whitten effect. The exposure of a recently bred mouse to the pheromones of a strange male mouse may prevent implantation (or pseudopregnancy), a phenomenon known as the Bruce effect.
The average gestation period is 20 days. A fertile postpartum estrus occurs 14-24 hours following parturition, and simultaneous lactation and gestation prolongs gestation 3-10 days due to delayed implantation. The average litter size is 10-12 during optimum production, but is highly strain dependent. As a general rule, inbred mice tend to have longer gestation periods and smaller litters than outbred and hybrid mice. The young are called pups and weigh 0.5-1.5 grams at birth, are hairless, and have closed eyelids and ears. Cannibalism is uncommon, but females should not be disturbed during parturition and for at least 2 days postpartum. Pups are weaned at 3 weeks of age; weaning weight is 10-12 grams. If the postpartum estrus is not utilized, the female resumes cycling 2-5 days postweaning.

Newborn male mice are distinguished from newborn females by noting the greater anogenital distance and larger genial papilla in the male. This is best accomplished by lifting the tails of litter mates and comparing perineums.
