On the internet there is alot about people's snakes with RI's making sounds (clicking, whistling, wheezing, sneezing). Over the years this has led me to become very paranoid when any of my snakes make even slightest noise. There have been 5 cases where i thought a snake had an RI but ended up being healthy.
Couple examples are when I used to have a big 9 foot boa, and she would always have a whistling sound to her breathing. No RI just the way she was. before and after shed. i got her checked out and i couldn't figure out what it was (maybe nose rub damage from before, or damage from live food etc..) I also had a bp who would kind of squeek the odd time especially at night. and now my retic makes these tiny breaths with the tiniest bit of squeek in them, but he has no RI, i've had him checked and everything he is perfectly healthy. (and by the way gotten alot bigger. will post pics sooon)

There seems to be a difference betweenthe sounds these make ^ and snakes who actually have RIs.

But is a healthy snake really absoloutley silent? Ive spoken to many people about this. Some tell me YES. a snake who squeeks or breaths loudly is not ok. Some tell me that snakes are different, and some are just more noisy at breathing, especially boas and pythons. The larger the louder.
I noticed it happens more in LARGE species. I'm staring to think some snakes are more quiet than others when it comes to breathing. I want to hear what YOU guys have to say about this, and what your experience is. Am i a little too paranoid?
