Here, have a nightmare... this is my daughter with her pet snake Brownie. Brownie is a Boa Imperator who, when this photo was taken was about 8 feet long. At this size, she eats what we call jumbo rats. They weigh about half a pound. As you can see, my daughter is terrified at this super predator that is about to eat her... Sigh.
Seriously, a boa is not a threat to anyone.
