Fey likes to hang out on the windowsill, behind a bedsheet, and cuddled up to the air conditioner duct. She was there today when I took out a pen and started swiping it along my side of the bedsheet. This is the result:

A pen, a window, a bedsheet, and a cat.

[Video shows Fey’s silhouette batting, grasping, and biting the pen through the sheet. All sounds are just the various scraping and other noises made by the activity, there’s no words.]
