A bunch of truly annoyed cats (and one sad chug) looking sharp on Dress Up Your Pet 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.

These cats do not want to save the day.

These little jaws will end your summer.

This little kitty just can't wait to be king so it can seriously banish its owner.

This little feline does not choose you.

This miffed cat wishes a plague of skulltulas on your house.

And... this dear thing. Someone help.

Ah, for good measure, look at this very good dog:
