I was reading this article, and it kinda gave me goose bumps. Simply because I have seen my two cats acting weird, when I saw nothing!

One day, both cats ran to the bottom of the steps. They were crouched down, and one of them was growling. You could see both of them moving their heads at the exact same time as if they were watching something moving. I looked up the steps and saw nothing.
The other day, my cat was sitting on the table. All of a sudden he looked at the steps and started growling. Then it was like he was watching someone walk down the steps, into the dining room, and then back to the steps. The whole while he wouldnt stop growling and his eyes were as wide open as I ever saw them. Just a little weird! They do this quite often.
So for those who believe in ghosts, do you believe animals may be able to see what we cant? Do your cats or dogs ever do that?
