Kitty Has Special Way of Alerting Owner She Wants Inside

Occurred on January 15, 2019 / Oud-Turnhout, Belgium

Info from Licensor: "My cat knocks on the door and says thank you when she enters. Her name is Koosje and she’s about 13 years old. She always does this, so I found it normal until the video went viral. If I don’t immediately open the door, she keeps knocking every 30 seconds. She’s very shy, but once you start to pet her, she won’t let you stop."
