I'm looking for certain terror movie, or maybe it was a chapter from some series, the plot goes like this:
A rich woman marries some guy.
They have their honeymoon at her house.
They were on the bed (nothing sexual shown as far as I remember), and the guy "playfully" put a pillow over her head while both where laughing.
At the third or so time of doing that, he finally do it until killing here from asphyxiation.
Then there's this scene where the guy is using a blender, and it seems one of the woman fingers was there, and the guy just rips a ring from it.
Then the guy feeds the blended meat to the cats in the house (the woman had a lot of cats).

I can't remember what else happened after that, and I'm wondering if anyone here knows where it may be from. I think it was from the 80's - 90's.
