Answer the question with Bomb, Old Age, or SPLAT (make sure everything is spelled correctly, capitals are correct, etc.) and watch the cat DIE. Sometimes it glitches so a bomb drops from the sky, blows up, and doesn't let you do anything. If this happens, press the green flag and try again. Feel free to remix and fix this.
Thanks to RoosterDBomb, obviously. Everything that's not done my them is done by me.
