I suspect everyone in this group is already familiar with the territory covered on this BBC related website
, but just in case...
- everybody knows that cats meow, but they only do it to humans. Cats don't talk to each other using meows at all, and we'll explain why later in the section on cat psychology. The meow generally means that the cat wants something from the human, perhaps to go out, or in, or out again, or some food. Food is always welcome."
