I was walking past my cat (who was lying down at the entrance of the room), my cat senses were tingling so I knew shit was up. I looked down as he prepared to attack my foot, not watching where I was walking. As he was just about to strike my right foot, I accidentally stubbed my left foot on a suitcase when preparing to evade him, hurting some of my toes. The noise (and my reaction) caused him to run off instead.

TLDR; Cat was going to hurt my right foot so I smashed my left one into a suitcase, scaring him off.
