The only time I remember being worried about animals stepping on me was on Isle Royale. Every morning at about dawn, the moose began moving. They make a lot of noise and they think nothing about walking through a campsite with tents. And there were a lot of them. Very disconcerting to hear such heavy hoof beats a few feet from your head.

By the third morning, I was accustomed to it. By the end of the week, it was welcome and kind of reassuring.
