Happy Halloween! & some art with cats

Happy Halloween!
What symbolizes Halloween to you most?  For me, a lot of imagery comes to mind, but most of all, I think of black cats.  

And how some people are frightened of them.  I found this out during Halloween when I was in first grade.

That Halloween afternoon we had a babysitter taking care of me and my siblings, and she just about jumped out of her skin that afternoon when Blacky, our family cat, came inside and crossed her path.

Since that afternoon, I associate black cats with Halloween.
