What’s the cat doing here? Its tail is up vertically, and it’s butting the dog with its shoulder, both of which are usually interpreted as friendly, social behaviors.
Does this look like the cat is trying to guide the dog, in an unbelievable show of understanding? Not so much. When the dog starts to veer towards the car, the cat doesn’t do anything. If anything, kitty is being kind of annoying, insistently butting in between the dog and whoever is holding the camera. If there’s anything unbelievable about the video, it’s that the little dog doesn’t seem to mind!
In short, what’s happening in the video is: nothing. It’s just a local cat trying to say hi to a dog, who is following its owner and not really paying kitty any attention. Meh.
