Final answer:
The transformation of the white spot into the image of gallows on the second cat in Poe's 'The Black Cat' affects the narrator by reflecting his guilt and foreshadowing his inescapable fate.
Step-by-step explanation:
The question relates to a narrator's reaction to a transforming white spot on a second cat, which evokes the image of gallows, presumably from Edgar Allan Poe's short story, “The Black Cat.”
In literature, such transformation typically leads the narrator to experience intense and complex emotions, often a mix of guilt, horror, and the realization of their own wrongdoing. This symbol of a gallows reflects the inner turmoil and impending doom that the character cannot escape. For further clarity, a passage from Poe’s story describes: “The image of the hideous – of the ghastly thing – of the GALLOWS! – oh, mournful and terrible engine of Horror and of Crime – of Agony and of Death!” Here, the gallows represent the inescapable guilt the narrator feels for his heinous actions, embodied in the white spot of the cat that has transformed to remind him of his inexorable fate.
