Rats (also called Pasyuki) found in every corner of the world.

There are decorative varieties of these animals that live next to a person as a pet, but this article will discuss about pest ratscausing irreparable damage to people.

Description and general characteristics

What kind of family do rats belong to? Pasyuki belong to the order of rodents, the family of mice. All over the world there are about 70 species of these animals, but in Russia only three types of rats are most often found: gray, black and red.

Rat size: body length, like the tail, reaches 30 centimeters. The minimum adult weight is 37g, the maximum can reach 900g (applies to gray pies)... The color of the skin depends on which species the animal belongs to.

Rats have very tenacious legs with movable fingers, thanks to them animals climb well and run fast.

REFERENCE! Most often they form large groups, a flock of rats lives in holes. Females are very fertile: in one litter there can be up to 22 cubs, but on average, their number is 7-9 individuals.

Dental system

The teeth of rats have their own characteristics. These animals have only two types of teeth: molars (3 teeth on each side of the jaw, 12 in total) and incisors (there are 4 in total, a pair of bottom and top).

Molars are located far away, their purpose is to grind food by chewing, so they are flat and wide. In rat pups, these teeth erupt from the 19th day of life, first molars of the first type appear, then the second. Third molars grow at the age of 40 days.

The incisors of these animals grow all their lives., with them the animals perfectly gnaw even very hard objects. These teeth fully grow in 50 days. The incisors are yellow in color, the enamel on them is very strong (5.5 units according to Mohs, it is equal to the hardness of steel). Incisors may move apart during chewing, this process is regulated by the animal itself.

How are rats different from mice?

Mice and rats belong to the same family. They look alike, but still between them there are significant differences... So, how does a mouse differ from a rat:

  • the size and length of the body (a mouse in length without a tail does not exceed 10 cm, but the pasuk grows to 30 cm, its body is noticeably more muscular);
  • tail (its length in mice and rats is approximately equal to the length of their body, but in the former it is covered with hair, and in the latter it is bald, very powerful and thick at the base);
  • the shape of the head (in mice, the muzzle is in the shape of a triangle, and in the beetles it is elongated, the nose is noticeably elongated);
  • eyes and ears (the eyes are small, the ears are small, pressed to the head; in mice, the eyes are well defined, the ears are large, stick out to the sides, have a rounded shape);
  • weight (the body weight of a mouse does not exceed 50g, and an adult rat can reach 900g);
  • the structure of the coat (in mice it is soft, in pies it is more rigid and coarse).

Rats, unlike mice, are able to jump high - up to 2 meters in an extreme situation. They are distinguished by high intelligence: these animals are on the same level of development with cats and dogs.

Food

Unlike many rodents, the rat is a mammal and needs animal proteins... What do rats eat in nature? In the wild, these animals feed on amphibians, fish, and molluscs.

Pasyuki catch and eat other small rodents, ravage nests and steal bird eggs. From plant food, they use grain and the juicy part of plants.

In towns and villages rats coexist next to humans... In this case, they feed on garbage, feed for farm animals and birds, and other products available to them. Rarely make food reserves of rats, the rodent eats about 30 g of food per day, they cannot stand a hunger strike and die already on the 4th day.

Can they swim?

They try to avoid water, however, rats can swim very well. An adult is able to stay in the water for several hours (up to 70), while she dexterously dives and gets her food... These animals hunt frogs and molluscs, so they are able to stay under water for a long time.

What are the footprints like?

Rat footprints resemble the prints of other rodents families of mice, but they have their own characteristics. The size of one footprint is about 1.5 * 2cm. The prints of the forelegs are four-toed, long toes set wide apart.

The hind legs of the Pasyuk are long, up to 4 centimeters long, but the imprint remains only from her half. Such a five-toed track, wide-spaced lateral fingers are visible. The size of the print is about 2 * 2cm.

What does a rat's footprint look like in the snow? The appearance of the chain of tracks depends on how the rat moves in winter. If she runs fast a thin chain will remain in the snow... If the animal moves by jumping, the tracks look like squirrels (the distance between them can be up to half a meter). Sometimes a tail print remains on the snow.

How do rodents harm?

Rats are pests. Very fast breeding of rats, causing serious damage to both farmers and villagers, and residents of the metropolis. Here why are rats in the country dangerous?:

  • carry severe infectious diseases: plague, tuberculosis, brucellosis, leprosy, rabies, typhus, hepatitis, etc.;
  • these animals destroy food products in warehouses and factories;
  • eat feed for farm animals and birds;
  • gnaw at the floors and walls of the premises;
  • disable electrical cables and various devices;
  • infect foodstuffs with helminths and salmonella.

Rats adapt perfectly to any conditions, moreover, they are very tenacious... These animals cause a lot of inconvenience to people and carry dangerous diseases, therefore it is necessary to get rid of them without pity in all possible ways.
