Cat does 'vacuum activity' jaw chattering while attacking a fly!

This is unusual in some respects because normally we see what is described as "vacuum activity" when a full-time indoor cat is looking out the window at a bird and they are instinctively compelled to practice the bite on the nape of the neck of the bird to kill it. Because they can't get at the real thing the domestic cat instinctively chatters their jaw and Dr. Desmond Morris calls this "vacuum activity". It's called that because it occurs in a vacuum namely there is no actual prey item in the cat's jaws. Some people call this a "tooth-rattling stutter". I prefer jaw chattering but you can name it what you like.
