Guys, it's been a very special day.

A day of delight for internet animal enthusiasts and overbearing pet owners, and the bane of existence for actual pets. It's Dress Up Your Pet Day — an actual, genuine thing.

Apparently started by U.S. animal advocate Colleen Paige, Dress Up Your Pet Day was designed to promote pet adoption and generally showcase pets for the delightful, dress-upable creatures they are.

Falling this year on Jan. 14, the day saw hundreds of social media posts featuring four-legged critters in tiny costumes.

We laughed, we cried, we picked out our favourites, including these very annoyed cats and one very disgruntled chug (pug-chihuahua).

These cats do not want to save the day.
