cats

I've hissed at him enough times that he knows how I hiss. Usually he scrambles and removes himself from the situation pretty quickly. The soda thing, coughs etc is more like "ugh fuck this" slowly getting up, look of disdain and moving somewhere else. Note that "somewhere else" is often a change from "in front of the keyboard" to "onto the chair that's next to me". I'd wager that it is more about the sparkly bit / bubbles making noise, than the hiss of the can.
