Mouse life span

Small mice can be the most dangerous pests that people get rid of by all means, all sorts of means or funny pets that you don’t want to part with. How many mice live at home, in the wild, with and without food, interests everyone. For the pet I want to create the most favorable conditions, for the pests - the worst.

Factors Affecting Rodent Life

The peculiarity of the digestive system of mice is such that the animals do not tolerate hunger, eat 5 times a day, every day they need to drink at least 15 ml of water. Such a “brutal” appetite of a small creature is associated with an accelerated metabolism. This factor is genetically determined and affects life expectancy. Under the most favorable conditions, the mouse cannot live longer than 5 years. The following factors shorten this duration:

  • Nutrition. A pet provides regular, nutritious nutrition to its owner. In the wild, a little mouse takes care of itself. And it’s not always possible to get a balanced feed. Malnutrition shortens the life span of mice. In the wild, in a relatively favorable environment, the animal reaches the age of 3 years.
  • Reproduction of offspring. The mouse becomes sexually mature 20 days after its birth. Pregnancy lasts about the same. Each litter has 3 to 11 cubs. 18 days after birth, the female is again ready for fertilization. However, the animal’s life cycle is affected by the number of pregnancies per year, the number of cubs, and the female’s health status. In the wild, a mouse reproduces a maximum of 3 offspring per year. The process is activated in the summer. An increase in this indicator significantly weakens the health of the mouse.
  • Living conditions. Mice adapt well to any environment, tolerate heat and cold relatively well, and live everywhere. All this thanks to the accelerated metabolism. However, climatic factors affect the period of life in nature, the ability to equip comfortable housing.
  • Threats and risks. The little rodent has many enemies in the wild - birds, foxes, wolves, dogs, hedgehogs eat mice. No less dangers in a person’s house - a cat, poison for mice, cell traps, traps. Weather disasters threaten life - floods, fires, frosts, early frosts.

Taking into account all factors, scientists have established a life span - 5 years, mice live in the home environment as a pet, 3 years in the wild. Since favorable conditions in the natural habitat are rarely established, the average life span of mice is only 1 year.

The effect of nutrition

It is recommended that your pet give a ready balanced meal. Since the mouse should eat in one day:

  • greens - 6 g;
  • grain - 12 g;
  • succulent feed - 3 g;
  • cereals - 3 g;
  • flour, including bone - 0.3 g;
  • fish oil - 0.1 g;
  • milk - 10 g;
  • salt - 0.1 g;
  • bread - 1.8 g;
  • feed yeast - 0.2 g.

Nuts, seeds give periodically. Abuse of these products leads to obesity.

Mouse nutrition
Mouse nutrition

The mouse is called an omnivore. Leaving it without food is almost impossible. To make up for my energy, mice eat everythingthat can nibble. With the threat of hunger in the wild, rodents move closer to the house of a person. You can always find food there.Assuming that the most unfavorable conditions have arisen, the mouse can live without food for about 10 days.

Important!

It is much more dangerous for the animal to be without water. In the absence of fluid in the wild, the mouse eats juicy parts of the plant. A pet locked in a cage, devoid of drinking, is in much worse conditions. How long an animal can survive without liquid is also interesting. The mouse lives without food and water for no more than 3 days.

Life threat

To catch pests, a person resorts to various methods, methods. Traps are ready to kill the mouse immediately or severely cripple. As a result, the animal dies during the day. Traps leave mice unscathed when it comes to the modern adhesive base.

On a note!

Recently, such traps from glue for mice are particularly popular. Easy to use, inexpensive, non-toxic. To find yourself in a deadly trap, just touch the glue with one foot. The animal tries to get out, performs various maneuvers, but sticks even more.

Caught in a glue trap, the mouse emits a terrible scream that you absolutely don't want to listen to. Many are interested in the question of how many glued mice live. About 3 days.

In the wild, the animal is at risk daily. Life expectancy in nature is much lower than artificial conditions. Few people manage to live up to 3 years. In a home cage with good nutrition, favorable living conditions, the ability to actively move, multiply no more than 2 times a year, life expectancy is from 3 to 5 years.

    My mouse died in a week while I was on a business trip. The drinking bowl clogged, water did not come to her. Now I am tormented by the question - died of thirst or by age. How old she was unknown. Trapped and tamed.

    1. Sergei

      Most likely from age. In nature, she quickly runs, actively moves, loses energy, thirst torments. The cage is not particularly scary. Moreover, it is not clear when the drinker clogged, not on the first day.

  2. Marina

    My mouse lived without water for 3 days, did not die. I forgot to add to the drinker. But left the grass. Maybe this saved her.

  3. Maksim

    On a sticky mouse trap, they live 3 days for sure. Most likely they die of thirst. But the timing failed. We leave a trap in the country. We arrive, we throw away the dead or stuck together with the constructed structure in the trash bin. Squeak scary.

  4. Svetlana

    Our mouse lived for 4 days with Velcro. They began to leave the house, heard that I had caught. We arrived after 4 days there are 3 more, but all alive, however, in a different state.

    If someone expects that the mice in the house themselves will die, it will not work. Leave without food, water is unrealistic. They will gnaw things, they will ruin the house.

  6. Olga

    Well, yes, they chew on paper, sharpen plastic, wood, in general, is a favorite treat. And they don’t have much water.

  7. Karina

    I am very afraid for my darling. I’m leaving for 2 days on weekends, I put her food, I pour water. But somehow I arrived, and the drinking bowl was upside down. She was terribly scared for her Mimi, if this would harm her. I read, calmed down.

    1. Anastasia

      You are kind, I also love mice!

    Do not worry so much. Mice are extremely resourceful, viable. They are killed ahead of time by their predators, people by poison. And they will always find food with water.
