-___- OF COURSE it's a cow,goat یا sheep. That riddle is so simple. I mean seriously. What other animals have utters? And for that matter what other animal does people drink the stuff from utters? -__-
EDIT: The cheese hint as well. Basically only three animals do humans even make cheese. Some people do drink لاما and اونٹ دودھ I believe but no one uses their دودھ for cheese.
