Hey everyone, new here. My BP is yawning back to back, has been for 10 minutes or so. Did it last night around this same time as well. He last ate 10\12, has been having normal poops, last shed was flawless. Eats every week without problems. There is no wheezing, drooling, bubbles or anything like that. He is also pushing his face against the tank and his hide. Once last night, and once just now he has made a very loud odd noise, kind of like a plastic grocery bag rustling, or a vibration. Any ideas? First snake, worried for his health. Oh, temps are fine, humidity is good. Edit: He does appear to have a little bit of substrate on one side of his mouth (inside). Not much, but its there. I use Zoo Med Eco Earth Compressed Coconut Fiber Expandable Substrate.
