Female Mice Eating Babies Essay

A mouse is a small rodent with a pointed nose, furry round body, large ears and a long, often hairless, tail. There are hundreds of types of mice, divided into subfamilies of either Old World or New World species. Common varieties include deer mouse, house mouse, field mouse, wood mouse, dormouse, spiny mouse and zebra mouse. 

Though some people talk about mice and rats as if they were the same thing, they are actually different types of animals in the rodent family. Rats generally are larger than mice, and they can be bald, scaly and cylinder-shaped.

Size

Mice come in a wide variety of colors and sizes. Some common mice colors are white, brown and grey. Some are very tiny and others are around the size of a baked potato. 

Mice typically grow from 1 to 7 inches (2.54 to 18 centimeters) in length and weigh between 0.5 and 1 ounce (.23 to .028 kilograms). The African pygmy is the smallest known mouse on the planet. It measures 1.2 - 3.1 inches (3.04 to 7.874 cm) and can weigh less than .35 ounces (.01 kg). These measurements do not include tail length. Some mice have tails that are as long as their bodies.

 

Where do mice live?

Mice are hardy creatures that are found in nearly every country and type of terrain. They can live in forests, grasslands and manmade structures easily. Mice typically make a burrow underground if they live out in the wild. Their burrow helps protect them from predators. Their natural predators are cats, birds, wild dogs and foxes.

Mice are nocturnal, meaning they like to sleep during the day. This is why pet mice or house mice can be heard playing or foraging during the night. Most wild mice are timid toward humans and other animals, but they are very social with other mice. Domestic mice are very friendly toward humans and can make good pets for older children and adults.

According to the RSPCA, mice are very territorial. Even domestic mice like to have a large area that they can claim as their own.

What do mice eat?

If you believe what you see in cartoons, you would think that mice eat cheese. Actually, they like to eat fruits, seeds and grains. They are omnivorous, which means they eat both plants and meat, and the common house mice will eat just about anything it can find. In fact, if food is scarce, mice will even eat each other.

Mice have voracious appetites. They eat around 15 to 20 times per day, so they build their homes nearby places that have readily accessible food sources.

Baby mice

When homes are infested with mice, humans will often find chewed up wires, books, papers and insulation around their home. Mice aren't eating these items, they are chewing them into pieces that they can use to make their nests. This is because mice nests are made from whatever the female mouse can find.

At around 4 to seven weeks old, a female mouse will mate and have young. She will carry her young for 19 to 21 days and give birth to four to a dozen babies, according to the University of Florida. Mice can have a new litter of babies every three weeks. 

Mice have unusual names. Females are does, males are bucks and babies are called pinkies because of their bright pink color. Baby mice are also called pups.

Pet mice can live up to six years, while wild mice usually only live around 1 to 2.5 years.

Classification/taxonomy

According to the Integrated Taxonomic Information System (ITIS), the taxonomy of mice is:

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Mammalia
  • Order: Rodentia
  • Suborder: Myomorpha
  • Family: Muridae
  • Subfamilies: Murinae (Old World rats and mice), Sigmodontinae (New World rats and mice)
  • Genera & species: Hundreds, including Mus musculus (house mouse), Apodemus flavicollis (yellow-necked field mouse), Apodemus sylvaticus (wood mouse), Peromyscus maniculatus (deer mouse), Micromys minutus (Eurasian harvest mouse) and Muscardinus avellanarius (hazel dormouse)

Conservation status: 

Most mice have healthy populations, though there are a few species that are endangered, such as the Alabama beach mouse. Massive hurricanes in past years have nearly wiped out their natural habitat. New Mexico's jumping mouse is also endangered due to wildfires, drought and other threats.

Other facts

Mice are much like humans in how their bodies and minds work. This is why laboratories use mice as test subjects for medicines and other items that may be used on humans. Nearly all modern medicine is tested on mice before they go to human medical trials.

Mice are tough little creatures when they have their minds set on a crunchy scorpion snack. They can withstand multiple scorpion bites. 

Mice can feel temperature changes and alterations in ground terrain through their whiskers. 

While communicating with each other, mice make ultrasonic as well as regular sounds.

Most mice are very good jumpers. They can jump nearly 18 inches (46 cm) in the air. They also are talented climbers and swimmers.

A mouse's heart can beat 632 beats per minute. A human heart only beats 60 to 100 beats per minute.

A wood mouse will shed its tail if the tail is caught by a predator.

Mouse Location

Mouse

The mouse is a small rodent that is spread widely throughout nearly every country. The mouse is found in all corners of the globe, including parts of Antarctica.

Many people today like to keep the mouse as pets because of the small size and quiet temperament of the mouse. The mouse is also used a lot in scientific research though the mouse is not an easy animal to examine.

The mouse is often easy prey around the world for small mammals, birds and reptiles. Due to this the mouse generally does not live for much longer than a few months in the wild, mainly because the mouse is small easy prey for many mammals and birds. The mouse though has been known to get up to a few years old when kept as a pet.

Mice can be harmful pests at times, through damaging and eating crops and spreading diseases through their parasites and feces. It is because of the pest problems caused by mice, that domestic cats are thought to have been introduced into common households.

The gestation period in female mice is less than a month, and the female mouse has an average litter size of about six baby mice, although the mouse litter size is commonly higher than six. The baby mice are known as pups and these mice pups are born with no hair and with their eyes and ears closed. Mouse babies are weaned when they are around three weeks old.

There are nearly 40 different known species of mouse found throughout the world. The different mouse species range in size and colour that is generally dependent on their environment.

Mouse Foot Facts

  • Mice have soft feet with nails on each of their toes that enables the mouse to climb well as they can wrap their feet around things.
  • Mice have five toes on their two back feet and four toes on their two front feet which gives mice more stability when standing on their back feet.
  • Mice use their two front feet to grip onto food such as seeds and berries, so that the mice can eat their food with ease.
  • The mouse has very small and flexible feet but it can easily get its feet stuck in areas that are too small, like if the bars on a mouse cage are too close together.
  • Like hamsters, the foot structure of mice enables them to run backwards into their burrows when wanting to escape from predators.

Mouse Teeth Facts

  • An adult mouse has 16 teeth which it uses for holding onto and chewing its food.
  • Mice have one upper pair and one lower pair of incisors at the front of their mouths which mice uses to grip onto and bite their food.
  • Mice have between two and five cheek teeth which mice uses for gnawing, but when mice use their cheek teeth the incisors at the front of their mouths stop moving.
  • The incisors at the front of the mouth of mice grow continuously to keep them sharp and strong, and mice must gnaw them down regularly to stop them front getting too long.
  • Mice tend to eat food that is hard so they can gnaw their teeth whilst eating meaning that although mice will eat cheese if they come across it, the myth about mice loving cheese is not entirely true.
