Anyone who says cats sneak around silently, has obviously never had a bunch of kittens running around their living room on a wood floor. It is amaaaazing, how these little guys can sound like there is a herd of buffalo stampeding through the front of the house.
(And if I am exaggerating, it is not by much. You can hear the thumpthumpthumpthumpthump-ing from nearly every room in the house, I kid you not.)
Oh, by the way, two of them (this boy and this girl,) are still needing homes, so if you know anyone in the Houston Metro/Harris County area who might be interested, please, please direct them to me. (That's right, the end of this post is a shameless attempt to push homeless kittens on y'all. I have NO MORALS.)
