Hi, I'm new to keeping snakes and I have heard My BP who I've had for about 3 weeks make whistling sounds. I'm not sure if he has an RI or stuck shed in his nose. He shed last weekend and it was in smaller pieces with some that was left over on his head. I got most of it off but I think maybe some was left behind and that could be the cause. Other than the whistling he doesn't show any other signs of an RI, He's always been really active and eats well. I've caught him yawning a couple times but nothing excessive. Please let me know what you think, as a new snake owner you can imagine this is making me a little anxious.
