Late the game, but when my BI female, Behira, now about 5-5 1/2 foot, strains herself climbing, or even quickly going through my hands and up my arm, etc, she can let out a puff. More of an exhale.
As stated earlier, a hiss would have open mouth and unhappy body language. Doesn't sound like that's what it is.
As long as she's not doing it all the time, and with open mouth, I would have no concerns.
As with any new animal, follow strict quarantine, but I think this is a non-issue.
