Interesting facts about mice

  • Mice are rodents. They are social animals, so it is good practice to keep two or three together, preferably all female.
  • Mice come in many colours.
  • They have open-rooted teeth, and so constant wear is necessary to maintain good dentition.
  • Mice live from one to three and a half years.
  • The doe (female mouse) may breed from six weeks of age, and gestation is nineteen to twenty-one days.
  • As baby mice are furless and helpless when they are born, it is important not to disturb the nest at this time. The babies' eyes open at ten to fourteen days, and they are weaned when they are nineteen to twenty-one days old.
  • Males reach puberty at five to six weeks of age.
  • Females may mate immediately after the birth of a litter, and so one litter is weaned as the next litter is born.
  • You can determine the sex of the young at four to five weeks of age and segregate the males from the females.
