I wish I didn't have to kill you but you left me no choice!
I once lived a very happy, peaceful life with my wife and 6 pets, being my dog, monkey, rabbit, fish, bird, and- my personal favorite- our black cat, Pluto. I grew up loving pets so figured why not get many?
As time went on, however, I grew to have a drinking problem. One day on a particularly bad night I came home to find my cat- the cat that I had loved so much and loved me back dearly- avoiding my presence. At first I felt bad, but that turned to rage that I took out on my cat by gouging out his eye.
Not to my surprise, the cat completely avoided me. I felt terrible at first; we once shared such a great bond. However, this eventually left me peevish, as I just couldn't stand seeing him run from me. I decided to end both of our pain by hanging my cat.
The jig is up, buddy!
Shortly after the death of Pluto I got a new cat that looked similar to Pluto, but with a white spot. At first I liked the cat but grew to hate him as he became too clingy. One night as my wife and I walked down to our cellar the cat got in the way and tripped me. I tried to kill him but my wife stopped me, so I killed her instead.
After the death of my wife, I found that that nuisance of a cat had left, so I was finally happy again. I chose to bury my wife behind a brick wall of the cellar and she was completely inconspicuous, so it was perfect.
A few days following the death of my wife, police officers stopped by. I gladly let them in, and after a quick look, they found nothing, and as they left I tapped on the wall that hid my wife saying, "Isn't this a nicely constructed wall?" I knew well I had won. Then a horrible shriek came from the wall, where behind it we found the cat sitting atop my dead wife.
