At the start of the video, we see a Super Mario Bros game being played, with the volume of the accompanying sound effects getting turned up.
Then a bushy-tailed ginger cat cautiously pads into the room, curious about the source of the music.
When a familiar note, which follows when the character Mario jumps, plays, the cat is jolted and jumps in shock, humorously mimicking what Mario does in the game.
It continues to get a fright each time that sound plays, still clueless on where the music is coming from. The video has at least 14,000 likes so far.
