laundry chute of Mystery

Our cat, MaeMay, is absolutely fascinated by the laundry chute. It is a hole cut in the floor, inside the second-floor linen closet. Any time the closet door is open--even just ajar--she is compelled to go in and look down the hole. Happily, she doesn't seem inclined to plunge *into* the Mystery Hole, but she sure spends a lot of time peering over the edge.

Now I'm trying to remember the article that said the "pleasure center" of the brain is more accurately named the "engaged/interested" center of the brain...

No wonder I like to read mystery novels.
