In "The Black Cat," compare the second cat with Pluto. How were they alike? How were they different?

The
narrator's first cat, named Pluto, is
described as "a remarkably large and beautiful
animal, entirely black and
sagacious to an astonishing degree." The narrator's wife is so
impressed with
the cat's sagacity, or wisdom, that she seems to suspect that it could, in

accordance with "the ancient popular notion," be the spirit form of a witch.
This
suggestion of evil is compounded by the significance of the cat's name:
Pluto is the name of the
Roman god of the underworld.

The
narrator's first cat, Pluto, at first
follows the narrator everywhere, and
the narrator is pleased to reciprocate the cat's love.
However, the narrator
soon becomes cruel and is seemingly possessed by a spirit of evil. He
starts
to violently abuse the cat. He cuts one of its eyes from the socket, and he then
hangs
the cat from the branch of a tree.

When he happens
upon the second cat, the
narrator notices that, in appearance, it is
remarkably similar to Pluto. The second cat is
"fully as large as Pluto, and
closely resemble[s] him in every respect but one." The
one difference between
the appearance of Pluto and and the second cat is that the latter has
"a
large, although indefinite splotch of white, covering nearly the whole region of
(its)
breast." Pluto, by comparison, was black all over. The second cat also
resembles Pluto
physically, conspicuously, in that it too has only one
eye.

In terms of its
behavior, the second cat, like Pluto,
at first follows the narrator everywhere. However, whereas
Pluto followed its
owner lovingly, like a companion, the second cat seems to follow the narrator

ominously, like a ghost haunting its victim.

Indeed, the narrator
remarks
that the second cat would follow him with "a pertinacity...difficult
to make the reader
comprehend." The implication of the story is that this
haunting, stalking pertinacity is
because the second cat is a reincarnation
of Pluto, returned from the dead to avenge its
death.
