Essentially, everything the speaker owns is swallowed up by the fire. He awakens in the middle of the night to find that the curtains surrounding his bed are in flames, and he soon sees that the "whole house" is ablaze. Only the speaker, his wife, and servant are able to make their escape from the fire. However, he says,
My entire worldly wealth was swallowed up, and I resigned myself thenceforward to despair.
Everything in his home, all his worldly goods, anything of any value that he and his wife owned prior to the fire, are all gone. The house itself is completely burned to ruins, and there is simply nothing left to recover once the fire is finished.
The speaker visits his ruined home the next day, and he notes that all of the walls have fallen in but one, a further sign of just how hotly and devastatingly the fire burned. Many people have already gathered around this one wall, and they exclaim in surprise and wonder at something they see there. The narrator approaches and sees, "as if graven in bas-relief upon the white surface, the figure of a gigantic cat." It is his cat, the one he hanged by the neck in his garden, as one can even see the rope around the cat's neck. He tries to explain away the cat's condition and appearance in this place but continues to feel haunted by it.
