What do you know about mice? Here are some fun questions and answers about these tiny mammals.

Mice are characters in many popular children's books, including Fiona the Theater Mouse. These facts are an excerpt from the study guide that goes with the chapter book.

This page will share some facts about mice that you may want to know.

Facts About Mice

Mice really are everywhere! You can find varieties of mice in all corners of the globe and living in all climates. But mice are good at hiding. You may not see a mouse very often, but that doesn’t mean there may not be mice living nearby. 


Mice are rodents, just like rats and squirrels. What all rodents share is that they have sharp front teeth that never stop growing. Rodents are a sub-group of mammals, which means that a mother mouse gives birth to her babies and feeds them with milk from her mammary glands. 


There are many different kinds of mice, some of which only live in a small area and others of which are spread across continents. North America is the home of hundreds of types of mice. 


The mouse’s closest cousin is the vole, which is often mistaken for a mouse. The vole is a little bigger than a mouse but has smaller eyes and ears and a shorter tail. Its common name is the field mouse. 


The deer mouse is found all across the continent while more specialized mice, such as the Sitka mouse, can only be found on some of the smaller Haida Gwaii (formerly called the Queen Charlotte Islands) off the west coast of Canada. 




What do mice eat?

In general, mice are not picky eaters. Depending on where they live and what kind of mice they are, mice will eat whatever they find close at hand.

A deer mouse’s favorite food is seeds, though deer mice may enjoy fresh buds and even new leaves in the spring time.

A meadow vole finds grass very tasty, but will also eat roots and seeds and bark.

Most mice also enjoy the occasional bug or caterpillar to round out their diet.

And, of course, if a mouse lives in your house, you may find little nibbles on the bread bag or on your apples or frankly on any food item you may leave out or that they can get into! 


What are mouse nests like?

Mice build their nests in hidden places. Outdoors a mouse nest can be in a hollow log, in an underground burrow, under rocks, or anywhere that feels private and safe.

Inside a mouse may choose to build a nest inside the walls or in a hidden place in your basement.

The nest itself is made with grasses, twigs, fur, cloth, string, yarn, or whatever the mouse finds handy. The mouse hollows out the inside and lines it with the softest material it can find -- moss, fur, or the down from thistles or milkweed or another plant. 


How many babies does a mother mouse usually have?

Mice can begin to mate when they only three or four months old. The male and the female will share a nest for a few days and the babies are born three weeks later. Depending upon how well the mother has been eating and her age, a mother mouse can have a litter of five to seven babies, but could even have many more. 

Newborn mice stay close to their mothers, nursing almost constantly for the first few days. At birth they are less than four centimeters (one and a half inches) long from head to tail. They have no fur and are blind and deaf. But after only four days or so, their fur has started to come in and after a week, they have doubled their birth weight. They can see at two weeks old. 

Some father mice help the mother take care of the little ones, keeping them warm and clean and teaching them how to find food. After a few weeks, the babies are all grown up and ready to strike out on their own.

How long do mice live?

Mice live for about a year and a half. This doesn’t seem like a long time to us, but for a mouse, it’s a lifetime!

They really are cute, especially when you watch them up close. I think the phobia has a lot to do with the way some mice take over our houses and get into everything. Not so great for our health. Still, I agree, they can be cute.

I love mice! I had one as a pet. Well, I just like to have weird pets, that is all. :)
They are really cute and funny. But many people are afraid of mice. It is common phobia. Never understood why, for they are such a lovely creatures.
Very interesting facts to be found in this article. And I adore those baby mice in the video. :)

They sure can, Katie. And Samsara, it's always a bit uncomfortable to empty a snapped mouse trap. If they would only stay outside . . . .

WOW those baby mice are so tiny and cute. I have cats and our neighbors have cats as well, we don't see many mice around our street. Oh my after reading this I'm glad we have the cats on prowl as mice can really make for a few headaches.

Pastiche, you probably already know this, but be sure to check your wires under the hood before driving your car. Rodents can cause so much damage by chewing on them. Could be a safety issue.

Maybe the reason I've chosen a mouse as the main character of my children's book is because they've been a challenge for me to deal with in my real life, too! I have an allergy to cats, but have tried to have outdoor cats. Unfortunately, they aren't very safe in my neighborhood with all our wild animals. I'm working on finding a solution for that, but it's not easy. I lost two very well-loved kitties in the last year.

I have mice ... in my car. I am so dismayed to discover they've moved into my car over the past few days. I've tried everything to deter them - dryer sheets, noise, traps and what not. I hope they move out as the weather gets warm and the car heats up in the sun.

Oh my, now you've made me feel so guilty that I have two cats that love to hunt mice! My rickety old farmhouse used to have lots of mice and probably mice babies. But BusyBody and Chaos have taken care of that.

This page makes mice sound so darn cute! I've seen many different types of mice thanks to what my cat catches. I've seen tiny gray ones and long tan ones. I'm always happy when my cat catches a mouse that's been living someplace inside!
