in the case of garfield it's obviously the rule of funny in a comic (for getting #relatable content), but considering how much mondays are hated throughout the entire weekend-observing world, i'm certain that real world pets are definitely at least somewhat aware of the moods in play. i can see a real dog or even cat noticing their owner is feeling down. can they figure out the 7 day cycle though?

but if so, how many other animals can tell apart or even calculate the work week? do pigeons know not to bother showing up in the park on a weekday, and wait for the evening? if not pigeons, maybe corvids can?
