The Cat Theory

This isn't a story, this is a documentary of my life ending. I don't care if you don't read this, because it's mostly for the police, but now is your only chance, because I guarantee this manuscript is going to be classified soon after my death.
Why? Because I already know who my murderer is going to be. And when I turn out to be completely correct, and everybody will wish to have me back, if only to tell me that I was right all along.
But I'll be dead.
I'll be dead because my neighbor's cat is trying to kill me.
