Okay, the title is a bit flippant but it's a serious question. Any pet that was left outside from Sunday night through Tuesday morning would have perished in the cold. I heard somewhere that on Monday it was warmer at the South Pole, where it is ostensibly summer, than in Chicago. (Puzzler: what time zone is the South Pole in, or the North for that matter? Sounds like quantum mechanics - all and none at the same time.)
