Well technically Nick, it would depend on the range and the level of the danger. If she can use the control over a wide range, then it doesn't matter whether animals were trying to run away and if she used it during a fight which was reasonably small scale and not too noisy, then there would be plenty of animals to control. As shown, this series has rather big animals scattered throughout, even in cities. But I do see your point of it not being useful most of the time, since some of the most obvious creatures that would appear would be flying fish -_-
