Okay, so a co-worker of mine started all this with some cute cat pictures, now we're trolling the web for cat stuff like we've got nothing better to do than this. Here's some links to my favorites, some of which I can't believe I haven't posted already:

Possibly the best of them all: <a href="http://www.vikingkittens.com">Viking Kittens video</a>

A close second: <a href="http://www.rathergood.com/punk_kittens/">Punk Kittens video</a>

And this speaks for itself:

Too cute.
