A mouse's daily basis summed up in this image
A mouse is a genus of rodent used to control a computer. Prior to the invention of mice, a computers' cursor was controlled difficult-to-use, bulky primitive keyboards which nobody knew what to make of. Things all changed once Bill Gates saw a motionless, seemingly unconscious rodent lying in the middle of the street and subsequently stuck some chips and wires inside of it to supply it with energy.
Mice are known for their ability to bite people's faces off in mere seconds. The average mouse often engages in acts of being chased by a cat, binge consuming cheese, and being mutilated by nearby mousetraps all with a lack of any prudence. Some say the antithesis of mice are cats, and that's certainly true if you consider that cats are bigger, stronger, and are able to bite mice into smithereens. If you're a mouse, though, you'll be doing yourself a favour by avoiding anything that moves with intent to eat you.

Mice often sneak under tables, dressers, etc. This annoys humans, quite a lot, so they have to look for them under the table or whatever. In order for humans to do this, they need to perform the Jack-O Challenge Pose pictured to the right.
Anatomy[]
The anatomy of a mouse is simple; a typical mouse's appearance generally consists of a hard plastic shell (the mouse's main torso), a red laser, some buttons (big ears) and a central wheel (its face), and a long wire (its tail) that allows it to be attached to a computer. Mice do come in many different shapes and sizes, but what's also essential about the mouse is that it can control the movement of the computer screen's cursor whenever it scuttles around. Inside of the mouse's body secretes an electronic chip which allows itself to function.
