The Giant Rat is a recurring figure in urban legends across the globe, most famously in the labyrinthine sewers of cities like New York and London. Stories tell of rodents the size of small dogs, their eyes glinting in the dark as they scavenge everything from refuse to stray pets. While exaggerated, these tales often draw on kernels of truth: sewer rats can grow remarkably large under optimal conditions, and the occasional discovery of unusually hefty specimens feeds the myth. Folklorists note that giant rat stories tap into deep anxieties about urban decay and hidden infestations thriving just out of sight. The Giant Rat serves as a modern cautionary creature, symbolizing what happens when human excess and neglect breed things beyond our comfortable control.
