How old are rats?

Rats are animals that cause hostility in many people. Since ancient times, they live nearby human housing, causing a lot of trouble and spreading various infections. Therefore, the question of how many rats live, their wild and domestic varieties, what they eat, will interest everyone.

Wild rodents

Most common type wild rat, called pasyuk, refers to mammalian animals of the rodent order. They inhabit almost all continents of the planet, except Antarctica. Spread everywhere several centuries ago, thanks to ships sailing across oceans around the world.

This rodent has gray fur, strong hind legs, teeth gnawing everything and quite developed intelligence. Torso length gray rat is 15-25 cm, weighs up to 400 g, tail length - up to 19 cm.

In the wild, pasukas settle closer to water sources one at a time or in groups. However, most of them move to housing closer to the person, where you can find plenty of food and warmth. The life expectancy of a rat living in basements, in trash and other places in settlements is only 1-1.5 years, occasionally they can live up to 3 years.

On a note!

In ancient centuries, street rats were a real disaster for the population of cities and villages, because they were carriers of the most terrible infectious diseases - black plague, fever, typhoid, leptospirosis and others. Also rats spread diseases helminths, salmonella, etc.

In nature, a wild rat eats:

  • small animals: fish, frogs, mice, mollusks;
  • plant foods: seeds and grains of plants;
  • close to settlements with all edible products and waste.

Often settles in landfills and garbage repositories. During periods of famine, cannibalism is observed in their colonies - they eat their relatives.

How long a rat lives in nature depends on nutrition, rat speciesmortality at a young age, the presence of predators and actions by people who have been trying for centuries fight rodents.

Rodents living in uninhabited areas usually produce offspring 2 times a year, but city dwellers and domestic breeds that have better nutrition and warm homes can breed up to 8 times a year, giving birth to 1-20 babies each time. Part of the brood is eaten either immediately by the parents: the weak and sick individuals do not live long or die in the young growth stage. Rat cubs reach puberty at the age of 3-4 months, and the peak of fertility comes in 1-2 years.

On a note!

According to experts, the number of rats in the world exceeds 2 times the human population, and in large cities the population of rodents is at the level of population.

Domestic rats

Many people keep domestic rats, considering them cute and intelligent animals that are easily trained. The use of animals in laboratory work and their crossing allowed to breed a large number of ornamental species: rex, tailless, bald rats, satin, dambo, sphinxes and others.

How many years old domestic rats live, usually depends on the owner, who takes on the responsibilities of caring for his pet. The average life cycle is 2-3 years, individual individuals survive up to 5 years.

The life span of domestic rats is directly dependent on nutrition and living conditions. For example, rodents can eat a large amount of food and do it continuously, from which they begin to grow fat over time and acquire numerous diseases.

Interesting!

The oldest representative of rodents, who lived to be 7 years old, is listed in the Guinness Book of Records.

Therefore, the role of the owner, who wants to extend the life span of the rat, is to limit his pet in the amount of food, remove the remains from the cage in time, and also keep it clean. Periodically disinfect rat housing and destroy its smell.

For the health of the rodent’s teeth, it is necessary to put tree branches, stones, pieces of salt and chalk into its cage. Also, veterinarians advise to communicate more with their "companion": pick it up, treat it with delicacies: dried fruits, cheese, cottage cheese, etc. Domestic tame rats that feel the attention of their master, eat normally and do not get sick, can live up to 2.5- 3 years

For pet lovers, it will be interesting to know which breeds exist, how to feed and care for them, what diseases they have, and how many years rats have lived.

  • Sphinxes (hairless) - belong to one of the modern domestic breeds bred with the help of a mutation.

    I had a rat. Beauty with snow-white hair. I bought it by accident, going to the pet store for fish food. She was very clean and smart, sat on my shoulder, and we talked. I took sweets from my hands, knew my name and left the cage at my call. But, unfortunately, did not live long - only a year and a half, I was very upset.

  2. Veronica

    And we bought two boys at once: blue and dark gray. It turns out that they live better in pairs of the same sex, and we avoided the fuss with the birth of babies. They were fed with special grain mixtures, a cage, and cleaned. They loved to gnaw branches from fruit trees. One lived 1.3 years, and the second - almost 2.5, he really missed his friend.

      In my basement there were rats, so I poisoned everyone, and you drove drooling ...

      1. Veronica

        So they were wild basement animals, and these were domestic animals. We loved them very much.

        1. Sergei

          Then it would be better if they brought a hamster.

  3. Andrew

    I also had Rat, very smart and cool. He liked to sit on his shoulder all evening, while I was working on my computer. Lived 2 years.

    1. Igor

      Well, and I thought only the girls we have are lovers of rats.

  4. Irina

    The article is strange. A rat doesn’t need a wheel, it’s not a hamster. And the tail can hurt. It’s better to just let it run, my rats ran around the apartment until we got a cat. Then she only let out on the bed: I will cover with a coverlet, I throw cardboard boxes and rags, they rustle there, they examine. And charging, and entertainment.
