I can recall watching a movie sometime in the 70's- don't remember much about it other than a cat falling out of a window and a toddler saying something like- baby go boom-kitty go byebye. The other thing I remember is someone dying and having concrete poured all over them. I also seem to recall some old people in the movie and that it is set in the city- Does this sound familiar to anyone. Like I said, I was a kid when I saw it, but would love to see it again. Thanks
