So to eat the mouse ah

One mouse uses and optical sensor with a little led that blinks to let you know it's working. Sometimes the cat gets up on the desk and the little led starts to blink furiously. Since it's optical it doesn't have a tail so the cat usually ignores it. And apart from the led blinking it stays perfectly still. The cat doesn't recognize it as a rodent. Sometimes when the cat's been in room I find the mouse isn't were I left it. It will be under some papers or cowering by the monitor. One time the cat started swatting it around and it got so scared the batteries leaked all over the mouse pad.

I feel bad for the little guy but I don't know what to do. Maybe a mouse cozy that looks like a dog - but I'm not sure the cat has ever seen a dog or knows to be afraid of it. I could slip it in the drawer when I'm not using it, but I know I'll forget. Besides, I think it's afraid of the dark. So I don't know what to do.

i guess you new the mouse is missing

truth is your gona have to use a compiler to make 1

race you to the next a compiler
b programing language

ill tell u what was

to enable the correct curvature when drawing freehand/mouse the ratio of the distance the mouse moved on the mat could be set against the distance the pointer could move on the screen.
4 accurate curves the travell on the matt would be 3 or 4 times the travell on the screen

a simple program i remember saying

thinking about it makes it seem a little more complex

praps its a swiss mouse
