In S06 Ep21 of The Sopranos titled Made in America, there is a cat that the Soprano crew brought over to the office that was apparently a stray.
The cat is shown staring at Christopher's picture on the wall. The cat is heard purring and is moving it's tail while staring at the picture. The cat apparently does this all throughout the day. The picture of Christopher gets moved and the cat goes and keeps staring at the picture after it is moved.
Yeah, he does that. Sometimes most of the day. Just stares at Chrissy's picture.
Paulie is extremely disturbed by the presence of the cat and even more disturbed that the cat is enamored by Christopher's picture.
You see that shit? Does it all the time, he says. Look at him staring at that dead kid!
Is there any explanation from the producers/writers of the show as to the significance of the cat and why it is constantly staring at Christopher's picture? Why is Paulie so disturbed by the presence of the cat?
Note: There are A LOT of opinions and speculations about this everywhere on the internet. I am looking for an explanation from the producers/writers on the show (if there is one).
