You'd think RATS, instead would yield a whole lot more meat...
I suspect the bats they're eating are the large fruit bats and flying foxes, not the little guys we're used to. And people do eat rats. I don't know about in Asia, although I suspect they do, but definitely in southern Mexico. In Chiapas cavers have seen rat on a stick, cooked and ready to go like a kabob, in the markets. Mmm!
