CaptainHowdy gets a scratching-post shaped no-prize for bringing us news of the earliest yet known sign of feline domestication:

Man tamed the cat around 9,500 years ago, more than 5,000 years than previously thought, according to a find of an ancient feline skeleton in Cyprus.

Of course, it could also be argued this represents some sort of cultic sacrifice, but who knows. Maybe cavemen had to worry about irritated felines widdling in their shoes just like we do.
