If this situation were flipped and a bunch of dogs were at a tea party table wearing festive hats, we wouldn't be as surprised.
The video was shot in Taiwan and the cats' owner, Sammi, decided it was really important to celebrate her felines' birthdays. It worked for a few seconds ...
Our favorite has got to be the Hello Kitty hat, although all the cats look equally annoyed.
And Sammi has done this before. There are other kitty birthdays to celebrate, too, obviously.
We were always told cats couldn't be trained. Sammi, you could be making millions teaching people how to do this.
