Gunny, i hate to be the one to break it to you, but the cat always hears you coming (unless kitty is deaf- some are; they're usually white).
dogs have owners, but cats have a staff- i have had a cat in the household since i was (according to my mother, anyway) about two years old, and i can confirm this storied fact on an entirely empirical basis. also, cats have two hobbies, the first of which is to mess with their humans' heads to that maximum extent possible, whenever it is convenient to do so. (the second hobby is left up to the cat)
so, if you sneak up on a cat, they do notice. kitty is too polite to mention it, or pretends to be startled when you touch him (or her, depending on the sex of the cat, of course).
good luck with your future cat sneaking. hope i didn't spoil it for you.
p.s. - i like the stick
