The teeth of mice are soft and grow throughout life.

Rats do not have soft teeth and grow throughout their lives, and rats reproduce very quickly.

The reproduction rate of rats is very fast, so that other species are beyond the reach of the dust, each female mouse per year on average breeding a young mouse to join the population, a pair of adult rats will have 10,000 offspring after a year, can be described as ten generations in the same house, as the saying goes: one male plus one female, three years two hundred and five.

2. The teeth of the mouse keep growing.

Rats can grow up to 13 cm in their teeth, so they need to gnaw hard objects, especially in a state of non-hunger, they have to gnaw on hard furniture, doors, windows, and walls, one is to open up passages, and the other is to grind their teeth. Its bite is well developed, with a chewing force of up to 260 kilograms per centimeter and a frequency of 90 times per minute, which is quite destructive.

3. Rats can "see at night".

Although mice are colorblind and cannot distinguish between colors, they can detect moving objects in very dark environments and distinguish between objects of different sizes and shapes. The maximum distance can be 15 meters, but the object is gray, so use bright yellow or bright green as poison bait to reduce bird feeding.

4. Rats are greedy and can be hoofing.

Rats are greedy animals, due to the amount of activity, fast growth, its food is also very large, the food eaten by rats every day is equivalent to one-tenth to one-fifth of their own body weight, it is spoiled, damaged and soiled more, the rough estimate of the proportion of the three is to eat one, spoil two parts, stain four parts, plus even eat with the harm is greater.

5. The sense of smell and taste of mice are relatively developed.

Used to locate food and identify odors, it has a keen sense of touch, and its beard and stiff bristles allow it to move freely along walls and holes in the dark.

6. The sense of hearing of rats is very keen.

Rats are not only sensitive to small sounds that appear suddenly (sensitive), but they can also hear ultrasound waves (a type of sound wave with a frequency higher than 20,000 Hz) that vibrate (per second) less than 10,000 times and emit ultrasonic waves to communicate with each other, while humans and cats do not hear anything.

7. Rats have "bone shrinking skills".

Mus mus can drill through 6 mm pores, and brown mus can drill through any hole larger than cm.

8. The ability of rats to "jump up and down" is also very strong.

Rats can crawl over horizontal or vertical cables, or they can walk horizontally on any form of tube.

It grows for life, but it's not soft.

The rat had sixteen teeth, and in addition to a pair of upper and lower incisors, there were twelve molars. Incisors grow throughout their lives! Rats are rodents with chisel-like teeth, which are very powerful and can grow for life.

Scientifically, it can grow until the rat dies, and the reason for the rat's private morality is that the teeth are too long to eat, and thus starve to death <>

About 10cm.

How long can rat teeth grow?

If the rat does not grind its teeth, it can open up to 10-15 centimeters in a year.

A mouse normally has 16 teeth, and under normal circumstances, he has two front teeth on top, two front teeth on the bottom, and 12 molars.

I wish you a happy life and all the best.

Thank you for your inquiry.

Mouse. Target.

Incisors. It grows continuously, and it grows very fast, it is said to grow 3 cm per month, and if it is not worn out, it will grow to 70 100 by the time of old age

centimeters long. That's why rats like to swallow things. Many rats do not have the strength to grind their teeth when they are old, and the incisors are getting longer and longer.

Mouth. I couldn't close it, so I starved to death.

The long teeth of mice are the result of a long period of evolution.

Rats (colloquially called"Mouses"), mammals, rodents, rodents.

Its main characteristics are that the body is tapered, there are no canines, there is a gap between the incisors and the premolars or molars, the incisors are developed, there are no tooth roots, lifelong growth, and common rodents are ground short; Act quickly; Plants are the staple food, and some are omnivorous; There are many types.

After the teeth of ordinary animals grow, the lower end of the pulp cavity is closed, which leads to the interruption of blood flow, and the odontocytes are cut off from nutrients**, and the teeth stop growing because they cannot secrete the plasma teeth. As a result, rats often gnaw on things like wood, wires, etc., to wear down their teeth that are too long.
