breathing question

[Gio]

My girl is pretty big. She is active, eats great, husbandry is tip-top, but I will some times hear a very quiet hiss or a sigh. There are absolutely no other signs of any ailment and have seen on the internet some snakes are just "talkers"
Is this probably the case for my boa?

Nothing to fear. They breath air like we do and that huff/puff you hear is air exchange and nothing more. Carpet pythons are notorious for this, and my boa does it as well.

There is a Youtube video of a huge retic out for a cruise and you'd think there was an air compressor releasing pumped air in the background.

If she is big like you say, it will be a lot more audible than with a smaller snake.

Pretty cool if you ask me.
