Being a little paranoid for a pet-owner is a good thing...it shows you care & you're paying attention. Now you know more of what to look for, in case it happens
to progress & actually be an RI, or for future reference. Snakes have some unique issues (like bits of old shed skin getting stuck in their nostrils that can make
breathing noisy- who knew?) so until you have more experience (or read the right sources) it never hurts to ask those who've been keeping snakes a long time.
I wish there'd been a forum like this around when I got started keeping snakes.
