Can you tell me which movie this was?

[rca2000]

This is a MINIMAL information puzzle, too!!

Then I was a kid(say-5-7 years old or so) My family and I would go to drive-ins a LOT in the spring and summer. My mother and father both liked them, and they were cheap. As a kid, I liked them too--there was lots of little rides for kids and such--then too, sometimes the door was left open to the projection room,and I could see "some things".

As for the movies we saw-I recall Walking tall, Magnum force, Deliverance, severl John wayne movies, Several Disney movies, and a couple of lost classics like Brother of the wind.

BUT--There was ONE movie, the title of which has remained a mystery to me for well over 30 years now. It was something that we did NOT stay for. I only recall ONE scene, from the VERY beginning:

There was a guy and a cat in a dingy looknig room(probably apartment) and some guy appeared to be poisoning the cat. THAT was enough for my dad, and we all left at that time. It was probably 1973,74 or maybe 1975. NO later.

ANY ideas on that one??

Anyone?

Bueler??
