I am looking for the title of an 80's movie about a rich, talking cat who lived in a mansion.?

I really can't remember much about it other than the cat talked with a man's voice, lived in a big mansion and maybe was robber or catnapped.

It seems like he lived alone and had a big yard. The neighbor boy would visit sometimes. And it also seems like there were a lot of dark shots of the house, like at night.

My grandmother had it for her BETA vcr, so I think it would have to be made in the 70's or 80's. I am leaning more towards the 80's.

And it is not The Cat From Outer Space.
