Feels like your style of drawing/animation just doesn't fully convey the intensity of the stare(s) with this one. XD
Though... maybe that's intentional, cause maybe that old lady wasn't all that bad after all. May she RIP. Definitely didn't expect that end, but you managed to carry on the comedy a bit with the cat anyway, and keep it classy. No badmouthing the dead. Well done. And good story.
