It should come as a surprise to no one that Taylor Swift was excited about International Cat Day.

The "Shake it Off" singer took to Instagram's new Snapchat-like stories feature once again for some feline-related fun, this time commemorating the apparent holiday on Monday.

Swift posted a quick video of herself dancing around and lip-syncing to Shawn Mendes' "Treat You Better" while decked out in a pretty impressive dual-kitten sweatshirt. "Partying cause Shawn's bday & International Cat Day," she wrote over the video

Aside from being International Cat Day, Monday was also social media and music star Mendes' 18th birthday. Swift is clearly a fan.
