I have read a lot of stuff talking about RI. Talking about that the snake will open its mouth. Is this always the case or what. I have noticed my BP sometimes when he is out, and I am awake LOL. He will yawn like. I have not heard him make any noise while breathing, but I have notice his sides moving while breathing( Note I know there will be body movement while breathing...Just giving Details) I have not noticed any bubbles or mucus or anything. When he opens his mouth I try to peek in LOL.. His mouth well looks like a mouth. Is there any concerns that I might notice in his mouth to help with future problem(Hope they do not happen). Thanks for any input!!!
