So I've noticed the last day or two, occationally my baby bluey makes a whistling noise when he breaths, usually when he's wandering about. Being that there is no other issues im not sure if it would be a RI or not but he has been spending more time in his humid hide lately and his lights werent working for a couple of days. He is close to shedding based off of his color so im guessing that would be why he is liking the humid hide but im not sure. Could it be that he's got some shed in his nose from last time(which was not all that long ago) which is just causing issues now? It sort of sounds like a baby bird sound. In all, there is nothing else wrong with him, still eating, drinking, pooing and exploring. If anyone had any tips that would be great!
