"why is mouse called mouse?"

because it has a tail(cord).

because it like act as a mouse and its shape as a mouse .

Here is a picture of the first mouse built. As you can see it's a wooden box, with a huge ball for tracking. The original interface for moving a pointer on a screen was developed by Xerox. They used what is called a "track ball", and it was later developed into the mouse, to make it more user friendly.

i have no clue. but its an ok name. my dad makes mouse noises at me when hes looking for batters for his... hes weird.. :P

a mouse is called a mouse because of it's shape and the cord resembles a tail.

in italian language it suond like "topo" or "ratto", therefore in italy the mouse is called mouse...
