A cat wears a paper bag GIF

Trust me, this cat isn't angry at all. They always look like they are but that's because of the shape of their eyes.
No, that cat is pretty darn happy, as he blinks slowly, shows no sign of stress or anger (a cat wagging its tail would mean it's pissed).~

I forgot to add, his tail is pointing upwards, showing his interest into that comfy bag.
