The Top Ten
Mice can squeeze through tiny holes

Mice have a remarkable ability to fit through tiny openings that are much smaller than themselves. Some mice can make it through gaps as small as 6 millimeters, which is smaller than half of a dime!

Mice can sing

Mice are among the four mammals that can sing. Joining mice on the list are whales, bats, and of course, humans. Male mice will serenade the females they are courting with an ultrasonic song.

Mice and rats have teeth that never stop growing

This is true for all rodents; their teeth never stop growing and continue to grow throughout their lifetime. They usually need something to chew on to keep their incisors trimmed.

The fear of rats and mice is called musophobia

From the Latin word "mus," meaning "mouse." It is also known as "murophobia," from the word "murine." This word comes from "Muridae," the scientific term for the family of animals that includes mice and rats.

Mice and rats can spread at least 35 diseases to humans

According to the CDC, these diseases include salmonellosis, hantavirus, and rat-bite fever. The infections may be spread through droppings, urine, saliva, rodent bites, or through fleas or ticks that have fed on an infected rodent (like the bubonic plague!).

A female mouse can have up to 15 litters in one year and can get pregnant again 24 hours after giving birth

For one mouse, the average litter size is 10-12. They can start to reproduce at only six weeks of age, so it doesn't take long for a few mice to create an infestation.

Rats are vulnerable to peer pressure

Scientists found that rats will force themselves to eat food they don't like if they know that some of their fellow rats have eaten it.

Rats are among the smartest animals on the planet

Often ranked in the company of dolphins and chimpanzees! They can memorize routes and solve puzzles, which means they can often find their way back into a shelter if their "usual" entrance has been blocked off.

Rats can hold their breath for a long time

They can hold their breath for a long time and tread water for as long as three days.
