Smaller mammals have shorter gestation periods. If a mother mouse kept her young inside her uterus/placenta for too long, the young would become so big that the mother would die. Also, mice have very short lifespans due to their heavy predation and small size, so a female mouse needs to produce as many young as possible in her short life in order to keep the species from going extinct. A short gestation period increases fertility in that more litters can be produced in the same amout of time. Thus, mice have evolved very short gestation periods. Although a mouse's gestation period is only about 20 days, there are some mammals, such as certain opossums, whose gestation periods are even shorter.
