John,
How do you know your cat's speech has no linguistic content?
Are there no cat whisperers?

At the moment there are 3 cats outside my window yelling and crying "it is
cold and I want milk".
(I am pretty sure that is what they are crying.)

(My neighbor better do something to shut them up very soon.)
