Abandoned alleys of Taiwan's bustling cities hide a secret. A cat, its coat as black as the night, has a fetish that's as unique as the island's culture. It's not just any cat, it's a connoisseur of the unusual, a master of the rear entry. With a flick of its tail, it positions itself, the city's neon lights casting an ethereal glow on its sleek form. It's a dance, a ritual, a testament to the unorthodox desires that lurk in the heart of this vibrant island.
