Mice have the tendency to breed all round the year. They possess the ability to turn a 4 mouse family into a 50 mice family within 3 months. Overall,they can produce more than 100 babies in a year. While male mice can attain sexual maturity at the age of around 8 weeks, female mice take only 4-6 weeks to be sexually active. Baring this in mind, the overall rate of reproduction doesn’t come as a surprise. Although many of the baby mice are taken by predators, the above numbers are still quite alarming. The average gestation time for a mouse is generally 19-21 days. Baby mice are referred to as pups. Female mice reproduce in the form of litters. Each litter normally contains 10 to 12 pups.

 

The rate of reproduction of mice tends to decrease due to a number of reasons.These can be inadequate nesting materials, malnutrition, tumors, inadequate light cycles and many other factors. At times, due to unavailability of food and water, female mice will eat their own babies. The lifespan of a normal house mouse is generally 1 year.

Mice make their nests to provide shelter for their babies. At first,they build their nests outside, keeping in mind the ‘search for food’ factor.However, the best place to live for a mouse family, is  your house, be that in wall cavities or your attic.It keeps them and their babies safe from predators such as foxes, owls and cats.Indoor nests for mice are normally made up of fibrous materials such as pillow or furniture stuffing, carpet fibres and shredded cloth or paper, and are around 5 inches across. Outdoors, mice might also line their nests with fur, feathers, shredded cloth, as well as grass and shredded wood.

As the chill of winter approaches, mice tend to migrate their nests back inside, again. Therefore, the best chance of stopping a mouse infestation in your home can be stopping them from entering and creating their nests in the first place.

Mice are social animals, and they take care of their offspring well. But there are a few odd facts about them. A female mouse normally wants to mate with the ‘strongest’mouse available (also called as ‘alpha male’), as she wants her babies to have the best chances of survival.It is also believed that a female mouse may abort and reabsorb her fetuses
