How about a heads up, cameraman?

After watching this video, the question isn't about why a cat would attack a defenseless dog napping on the couch, because we know the answer--cats can be massive A-holes at any time for no reason. The real mystery surrounding this video is how the dog could possibly fall asleep in that house in the first place?

Whenever we post videos of big dogs being afraid of cats, many of the commenters express wonder about how a big dog could be intimidated by a much smaller cat. This is why! The dogs are terrified of winding up on the cat's hit list and never being able to sleep soundly again.
