Just personally, I would "error on the side of caution" if I were you...you can still SEE & ADMIRE hognose snakes, but there are SO many awesome snakes to
keep, why not choose one that carries no extra risks? Just because no one has ever died from a hognose bite does NOT mean that's been 'tested' with anyone
who is immune-suppressed. Sometimes the doctors just don't know what events can be set off.

Most doctors aren't that "into" reptiles & caution against them for the salmonella risks (posed mostly by turtles, not snakes). I'm pretty sure their answer to you
keeping even a "mildly-venomous" snake would be "please don't", and on this, for your sake (& Katie's & your family's sake) I would agree.

It's up to you of course...this thread started out as a mission to talk you out of adding yet another snake, I think we've done our part, LOL!
