Why? Because there's nothing else like them. Most responsible giant keepers are awed by them in a way that no other snake can.

A: yeah exactly.. that's one reason why they are so awesome!

B: nope.. but as said, constriction can. People who are constricted by their pet snakes usually made a stupid feeding error.. most of the time it is a mistake the keeper made that gets them into trouble. That's why inexperienced people shouldn't have giants.

C: so can your car, your dog, your horse.. etc etc.

D: well that depends.
