The 'Happy Happy Happy Cat' meme features a video of a small cat jumping and clapping its paws, usually accompanied by the upbeat 'My Happy Song'. It first gained massive popularity on TikTok and Instagram in early 2023, often used as a reaction to express extreme excitement, happiness, or a sense of victory over small life wins. The footage itself is a cutout of a cat from a viral video that was later paired with the catchy tune to create a 'wholesome' meme trend. It often appears alongside other cat characters like the 'Banana Cat' or 'Maxwell the Cat' in short-form storytelling videos that depict various emotional scenarios, becoming a staple of the 'Cat Lore' subculture.
