9 Interesting Facts About A Mouse


A mouse (if more than one, they are called mice) is a prominent part of the rodent family. Rodents are mammals with a pointy nose, round ears, a thin, long tail, and the ability to multiply quickly! House mice are the most common type of mice that we see infesting people’s houses. Some people also keep mice as their pets. A mouse can invade your home quickly. Mice are called ‘pests’ by many people because they are challenging to get rid of. 

Scientists also use mice in experiments. Most of the time, the mice are harmless, but some might carry disease-causing germs and illnesses. They eat almost everything. This is why many people hate having a mouse infestation in their houses. 

9 Interesting Facts About A Mouse

But, a mouse is a fun and exciting creature. Mice have many attractive qualities and are extremely cute. So, let us take a look at some fun facts about mice!

Basic Mouse Facts: 

  • Name: House Mouse
  • Scientific Classification:
    • Kingdom: Animalia
    • Phylum: Chordata
    • Class: Mammalia
    • Order: Rodentia
    • Superfamily: Muroidea
    • Family: Muridae
  • Latin Name: Mus musculus
  • Appearance (physical characteristics): Mice look similar to the other members of the rodent family. They are smaller than rats. Mice have a pointy nose, whiskers, a long, scaly tail, and round ears. They can have many colors that range between white, black, and brown.
  • Different Types of Mice: There are more than 30 other species of mice. The most popular ones are:
  • House mouse: A house mouse is called that because you can find it inside people’s homes. It is an unwelcome guest, and so people call it a pest. They can have brown or black colors. These mice can have more than a dozen babies every three weeks, so they are impossible to get rid of once they infest the house! They eat everything such as meat, dairy, and vegetables. 
  • Deer mouse: Deer mice are usually brown because they look like small deer. They are not common in people’s houses. You will find deer mice in forests, grasslands, mountains, etc. Because they do not live with people, they eat seeds, insects, fungi, etc.
  • Some other famous kinds are the field mouse and the wood mouse.
  • Size and Weight: A mouse only grows up to 2 inches in length. A typical house mouse weighs around 20 to 25 grams.
  • Habitat and Range: These days, mice are found in every place. Mice usually live inside the nooks and crannies of people’s houses or in abandoned places. However, their natural habitat is to build a burrow under the ground to live and hide in case of any threats.
  • Diet: Most of the time, mice eat everything they can get. By nature, they are herbivores. They enjoy eating fruits, grains, dairy products (and of course, cheese!) as well as food leftovers. If you have a pet mouse, make sure to feed it vegetables, fruits, and nutritious foods.
  • Life Expectancy: Mice do not live for very long. Their average life expectancy is two years. If they are not pets and live in the wild, they will live for even a lesser time.

9 Interesting Mouse Facts

1. Mice have horrible eyesight.

Mice can barely see anything at all. In bright daylight, they are practically blind. Their time to see a little bit around them is dimly lit. Not having good eyesight does not affect them much because their senses of smell, hearing, and taste are good.

2. The teeth of mice keep growing throughout their life.

Rats and other rodents have teeth that keep growing as long as they live. Research says that the rate of their teeth growing is 0.3 millimeters every single day. So if mice wish to reduce their teeth or if it gets in the way, they try to gnaw or chew on things to file their teeth down to a lesser size.

3. Mice have strange walking habits.

Mice travel from one place to another in a weird manner. They ignore the space in the middle and always travel near the walls or adjacent to corners – but never from the middle.

4. Mice eat more than 20 times a day.

Even though mice are so small, they have large stomachs that never get full. Mice eat more than ten times every day. You will find them on the hunt for food constantly. They visit their food sources more than 20 to 30 times and will keep nibbling on food at different places. Mice are omnivorous, so they enjoy eating everything.

5. Mice create a ton of mess.

Mice are small creatures, yet you will find their nests littered with droppings. Studies say that a house mouse poops so much that he produces more than 100 droppings in a single day!

6. Mice make excellent gymnasts.

Mice are good at most sport-like activities. For example, researchers have studied that mice (who are hardly 3 or 4 cm in size) can make a vertical jump that is more than 25 cm high! Not only that, but mice are excellent at climbing too. They can do rope-climbing like a professional and climb up to 2 meters high.

7. Mice have better ears than we do.

Even though they cannot see as well as humans, mice have excellent supersonic hearing. As a result, they can hear softer sounds than we can. These soothing sounds are called ultrasounds, and mice can hear up to 90kHz sounds. Like bats, whales, and other animals, a mouse can use ultrasounds to talk to other mice.

8. Many predators hunt mice.

Mice have a lot of predators. This is why they cannot survive on their own in the wild—animals and birds like eagles, snakes, cats, foxes, owls, etc., can eat them up. So they can only live up to 2 years of age when they are in captivity or kept as pets. Many rats are also used in experiments, which helps them live longer.

9. Mice are famous in pop culture.

Many famous characters in popular culture like movies and cartoons are mice. Mickey and Minnie Mouse from Disney, Remi from Ratatouille, and Chuck E. Cheese are the most well-known.


Mice are fascinating creatures. As cute as they look, they can cause a lot of harm if left unchecked. They carry a lot of germs, and if you are not careful, they will spread diseases around your house. You may have to call a professional to make them leave your home. On the other hand, if you are keeping a mouse pet, you will be entertained and will enjoy spending time with these little creatures. They are easy to feed, care for, and are mostly self-sufficient. We hope that now you have learned more about mice than you knew before.
