No...so what's your explanation for the 2 videos not being weird ?
Okay, now you're completely going over the edge, R1.
Cat video: Do you think that the person holding the video camera is invisible? Can cats sense people or other animals staring at them? Why yes, they SENSE it with their hearing, sight, or smell. Ya think maybe it might've heard some noise from behind?
And as Arthwollipot was leading to, anyone who's ever owned a cat knows that one of their most endearing acts is that they will decide, on a moment's notice, that they need to be on the opposite side of the house, at the fastest speed their legs can manage. That's just what cats are like.
Prairie dog video: Huh? The video jumps from camera to camera. How do you know what's on the other side of that plexiglass panel out of camera range. Further, the little critter is running around through the whole video, checking out every angle. AND THERE ARE PEOPLE EVERYWHERE!
In both cases, you see an invisible stimulus? That's easy - we're back to the dragon in the garage again.
ETA: Prarie dog.... actually the little fella is heading for one of the girls in blue shorts, so there's actually no possibility of there being something invisible or that he'd notice it, as there is just too much consternation on all sides.
