Mice are exceptional little swimmers. Some studies show that they can tread water for up to three days, and can hold their breath for up to three minutes. Mice can swim up to 1/2 mile before getting exhausted. Don't worry about mice swimming up your toilet, though; that activity is usually reserved for rats.
Mice do, in fact, have backbones. It's a common myth that they don't. What they also have are sloping, flexible collarbones, which makes it incredibly easy for them to sneak into holes the size of their heads. They also have very flexible ribs, which makes wriggling into tight places a cinch.
While it's uncertain the origins of mice, it's believed that they coexisted alongside the dinosaurs. When a comet hit the earth 66 million years ago, the larger animals died off and the smaller ones flourished.
They started in Europe and Asia and eventually made their way over to the New World on boats, where they exist today.
Early mice had to be small and inoffensive to avoid being picked off by larger predators, and it's speculated that this is what they looked like:
They eventually evolved into the form that we know them as now.
Mice out in the wild will make a home out of any available space. It's harder to get by in the wild because they're more likely to get eaten by predators, so they have to be extra careful when choosing a place to hide. You can find them in the city as well as in the prairie, mountains, or even swamps.
You can find mice in the following places in the wild:
- In knotholes in trees.
- In piles of rocks, in caves, or in rock walls.
- In piles of leaves and mulch.
- In unused sheds and cabins.
- In abandoned farm equipment or cars.
- In piles of firewood or lumber.
Some mice like to live in burrows or holes.
Some of the types of burrowing mice include:
- Wood Mice.
- Oldfield Mice (also known as a Beach Mouse).
- Yellow-Necked Mice.
- Deer Mice.
Not all mice are burrowing mice, though, and will prefer to come indoors or hide in other places above ground.
Sometimes mice will even eat their own young. It's very rare that they'll do this, but if they do, it's because they're stressed or their nest has too many young in it. If the baby mouse doesn't seem like it'll survive to adulthood or it's sick, that's another reason that the mother mouse will eat it.
In times of famine, a mouse will hunt and kill another mouse for food. It's extremely rare, and not their preferred source of food, but a starving mouse isn't going to say no to a meal when it has no other choice.
Mice are opportunistic foragers, which means that if they encounter a dead mouse, they might eat it. If they don't have sufficient food, that makes a mouse stuck in a trap an easy meal.

In 77 A.D., Pliny the Elder said, "The elephant hates the mouse above all other creatures." Today, that statement is hotly contested and some people scoff and say it's an urban legend. Others strongly maintain that elephants are, indeed, afraid of mice. Which is the truth?
The common belief is that the mouse will crawl up the elephant's trunk and suffocate it since elephants have no epiglottis (the cartilage that closes the windpipe). However, that is unverified. What's most likely is that any sudden move is startling to an elephant, causing it to flee in fear. So in actuality, it's not the mouse that the elephant is afraid of: any small, scampering animal can trigger its startle reflex.
Mice do many things by instinct. If they see a female mouse, they want to breed with her. If they see a male, they become get territorial and will pick a fight. Many of these tendencies are ingrained in mice and aren't taught - it's just part of who they are.
These are some reasons that a mouse will fight another mouse:
- The male is encroaching on another male's territory.
- They're fighting for a mate.
- Sometimes mice play-fight. (This is more common with young mice.)
- They're trying to establish dominance.
- They're hungry and food is scarce.
Mice are agile and nimble and are very fast runners. They can hit speeds up to 8 miles per hour – to put it into perspective, that's as fast as a human running 160 mph!
They're also very good jumpers and can jump one foot straight up into the air. Do you know what else are good jumpers? Fleas! To learn do mice carry fleas, please click here.

Mice are social creatures, and they like to live in pairs. Male mice, of course, can’t tolerate other male mice, but they’ll accept a female mouse. There’s a good chance they’ll mate if they live together. Female mice can also live with other female mice.
How do mice build those nests that keep them safe from predators and the elements?
It’s a multi-step process that is an ongoing work-in-progress:
- They first have to scout the area where they want to live. They need to make sure it’s warm and dry and away from predators like birds and snakes.
- They then have to harvest materials that they’ll use to build their nest. They may use old fabric from clothes, shredded paper, or insulation. If they’re outdoors, they may use grass, straw, or leaves and moss.
- If they’re planning for winter, they may stock up on food for the long, cold months. They’ll hide their food in or near their nests.
- Mice are prolific breeders and once they have their nest set up, they’ll reproduce.
- Once the surviving mice grow up, they branch off and start to build brand new nests of their own. Over time, 24 mice can blow up to be 2,000 mice!
