Realistically it's far more natural for animals because of the amount of data we have coming in to help us. Imagine walking across this terrain with your eyes closed, you'd be much much slower. Or just think about when you try and walk when your foot or leg is "asleep" and all you feel is pins and needles. Without all that sensory feedback it becomes very difficult very fast.
It's like asking where you hand is. You know where it is because you feel the joints, the skin, and the environment it's touching. Ask that of a robot and you'll probably have angle sensors, maybe a vision system to help, but there isn't way in the much of full on tactical feedback like animals have.
