Scream-Dubbed Cat Yawn Compilation

I'd say on the most part, funny videos on the net illicit a chortle or a "heh" out of me.  They're good, sometimes even great, but for whatever reason I just don't have any huge reaction  (unless watching with someone else, in which case we kinda bounce off each other laughter-wise).  But this... THIS... Made me lose my s*it.  There were tears, yes.  And all it took was a simple idea to dub yawning cat videos.  We've helped unearth a true gem.
