This is a story about THE CAT FROM HELLLLLLLLLLL!!!!!!!!!!!!!!!!11!! 
 Actually no. 
 This short story is actually about a man not controlling his impulses very well (a common Poe theme/character trait) and a cat that refused to let him get away with that fact. This story is very interesting to me because it leaves things open to interpretation (unless I'm missing something) as to whether events are supernatural or if the protagonist is simply insane. Like The Raven we have an animal that is obviously meant to represent more than meets the eye but we also have elements of The Tell-Tale Heart in that we have a narrator who is definitely not in a stable state of mind, and we learn during the story just how unstable he is. 
 Now, without going into debate about the cat's supernatural nature, one can legitimately wonder what allegory the cat is for. Does it represent truth, justice, punishment, God, the Devil (which I personally think given events in the story and the protagonist's own nature is highly unlikely), or something else entirely. I think it would be the first two but it can be argued for most of what I named. 
 I'd advise you to read this book and figure it out and if you have already read it ponder those questions and see what your answer is. Also, try to be nice to cat's, you really never know.
