Achievement notification sounds entered pop culture with console gaming in the 2000s, when platforms like Xbox began popping a chime and banner across the screen every time a player completed a challenge. Players soon learned the sound could turn anything into a victory, and meme editors began dropping the chime over real-life clips of tiny wins. A 'pet a cat' achievement fits that trend perfectly: many modern games reward players with an achievement for interacting with animals, and the clip borrows that familiar reward format to celebrate one of the simplest wholesome acts online.
