I was going to make the headline "The Grumpiest Cat in a Santa Hat That You'll Ever Stare at" but I thought the rhyme (?) wasn't good enough, better skip it. Did I make a big mistake? Secondly, check out all these p.o'ed cats! Their owners better sleep with one eye open and a shot gun in hand. Thankfully (?), this is America, so they're probably already doing that.
