My parents have a black cat like this. Perpetually grumpy and pissed off, even when being fed or scratched behind the ears. It will literally growl and purr at the same time.
Or any other fucknut for that matter, I've seen like 3 "ninja" the cat vids in the hopper at the same time. It is at the very least uncouth to submit your own grainy cat videos here, at least in my opinion. I like the vid enough, but there's evidence of foul play.
