Witchcraft/Occult movie?

[Kroogur]

  I saw this movie many years ago, I'm thinking it was maybe made in the 70's and the only scene i seem to recall was a young woman/girl trapped in a pentagram that was drawn on the floor and her sister? was a witch of some sort and she shrunk the trapped girl down and released her from the pentagram at which point a cat started chasing her.

Any ideas on this one?

Thanks for any help.

That was an anthology film called The Uncanny, about evil cats. I saw it on Showtime more years ago than I'd like to admit.

Each of the three stories is involves cats in some way. The segment you recall is from the middle story.
