Human beings need holidays to make ourselves feel special.
Now the way I phrased that sounds like a bad thing, almost like I'm taking a jab at my species. This isn't the case, however. I understand and fully get the need for having holidays. Going out of our way to feel special and celebrate life is a good thing, especially if we're struggling so hard every day to live out our dreams and hopefully fulfill them one day.
But it seems like all the good holidays are restricted to humanity and animals don't really get to join in on the fun. Sure, you'll dress your pug up for Halloween or get them a cute little Christmas sweater. But what about a celebration that doesn't involve them dressing up and looking ridiculous for our enjoyment?
