"It's a little like magical sensitivity, except animals don't react in special ways to enchanted things," says Shura's grandmother, "they can only tell the difference between daemons and animals. In people, being able to tell that easily and quickly usually comes with being able to tell things about magic. The faster a mortal could tell that Kalavar isn't a duck, the more likely they'd be to notice my dagger's enchantments, or my birth blessing, or tell that I'm not a mortal even if I dressed up like one. Of course witches have higher magical sensitivity than mortals do."
