I wouldn't be surprised if my cats see ghosts. I have a picture that came out weird. I was taking a pic with my cell phone. right before I snapped the pic, he looked to his left as if something just flew by (nothing there). the pic came out like this: http://i5.photobucket.com/albums/y157/darmom/fonzie.jpg
I took a second pic right away to see if it would show up again. It didn't. There was no smoke, spiderwebs or steam in the room, and a flash was not used for this pic. I am bald, so it's not my hair sneaking in front of the lens. I dunno.
