What I wanted to say is that according to the author, Humans are unique in the way they can "communicate about communication", while any other living being on Earth uses communication just to transfer information: "I am hungry", "I am in heat", "Danger", "I am poisonous, go eat someone else"...
Adding the metacommunication layer we can do much much more than just saying "give me the milk".
W. says that the meta-communication layer, for humans, is mostly a way to broadcast your own self-image and see how the others react to it.
How many different way to ask for milk you can manage? Polite, obsequious, commanding, rude... what are you trying to say to the guy handling the milk, besides the simple fact that you want some? Are you in a position of power? or are you appealing to his kindness?
So the reason the cat does not need this extra layer is because he only wants his milk, and it is not trying to impress you about his own coolness, or how erudite he is, and so on.
I’ve raised both dogs and cats. They most definitely have multiple ways to ask for food, or to go for a walk, or to say they are sick.
They can do it patiently, timidly, demandingly, angrily, etc. and there’s a progression: they might not say “I’ve asked nicely, you idiot, and you didn’t respond, so now I’m no longer asking nicely” - with words, but they do act it out.
Please read the book if you want to really argue this and the other points: I am not the author, I have to titles pertaining to psychology (or ethology/animal behaviour) so I might misrepresent the topic.
You, on the other hand, may very well be a workd-renowned expert on canine/feline communication but in this specific case are barking up the wrong tree: the cat example is not the main topic but more of an example/metaphor.
According to the book theories, your real intent in commenting (as revealed by the way you framed your remarks) is that you wanted to validate your self image of being an expert on animal behaviour, having raised plenty of dogs/cats.
One of the main thesis of the book is that metacommunication is an automatic mechanisms which is used by humans as a sort of sonar signal: every time we communicate with other we are sending out an image of what our self image is, hoping that their reactions will validate it (e.g. "I am trying to look cool, or learned, or authoritative or whatever, and I hope that the way you react to it confirms that my signal was received)".
In a discussion about a Pscyhology book (by a quite influential and respected researcher) you felt you really had to make known to everyone that your superior experience as breeder of innumerable dogs and cats made amply clear that the guy was a charlatan, due to a half-page example from a 304 pages book.
A book you have not read, and you probably did not even know it existed before another random guy mentioned it.
From this I infer that what you really wanted to say is "Hey, look at me: I know lots about cats and dogs."
I am not blaming you. This is exactly what Watzlawick considers to be one of the primary "uses" of metacommunication by humans: a way to project our own self image on others.
And I am surely doing the same, just like everyone else. Maybe I am a bit more conscious about this phenomenon, thanks to having read the book. ¯\_(ツ)_/¯
This isn't a good pitch for getting me to read the book. Seems like too much psychology being applied where it's not warranted, possibly leading to misunderstandings of sitcom proportions.
I knew someone who couldn't smoke weed because any time she did, everything seemed loaded with intent and backstory that seemed all too true.
Communication doesn't happen in a vacuum. I hope the book at least acknowledges that metacommunication received is subjective to the receiver.
