Most of us cats are NOT silent meowers. We do a proper loud meow that even stupid humans can hear.
Dumb they may be, but even the dumbest of humans can understand a meow when it is a demand for food. We are loudest usually at breakfast, when we have had nothing to eat during the night. "Meow" mens "I am starving."
Here my Spanish friend, Josephine, is making sure that her human, serves her breakfast as soon as possible. You will notice that he is talking back to her - even if it is a bit of a grumble. And he seems awfully slow.
But that is the usual human response. They can't help it. they just aren't very clever.
