What was the first CATGIRL?

Could you elaborate on the origins of the term 'CATGIRL' in the cryptocurrency and NFT space? Specifically, what was the first CATGIRL, and what significance does it hold in the history of this phenomenon? Was it a pioneering project that sparked the trend of feline-themed digital collectibles, or did it emerge from a different context altogether? I'm particularly interested in understanding the story behind its inception and how it came to be recognized as a pioneering example within this growing market segment.
