My family always had cats. They could see things we could not, all the time. They would look up and watch something move across the room that no human being present could see. And, sometimes they'd be in front of a cabinet or door and suddenly get their hairs up and back away, hissing. there was something there that only they could sense. I have always wondered what it was, but never doubted that there was something there. Cats and dogs don't make things up.
