Yes! Snakes actually shed the skin from their outer nostrils along with the skin on their face/head...so it's possible that was his only problem, but listen
closely for any whistling or crackling sounds, & watch to see if he breathes with his mouth open as before. If he's truly without symptoms before your
appointment, you might want to cancel & let them know what happened. But be very sure those symptoms are really gone. Fingers crossed...but I have
a hunch that he may still have an RI, it's just that it was more symptomatic due to the shed.
