i think my ball python might have a respiratory infection? sometimes he "yawns," but i've only seen him do that a few times since i got him almost a year ago. i've noticed a faint wheezing sound when he breathes, but it wasn't loud and it might not have even been coming from him. and sometimes when i hold him this clear, mucous-y substance comes from either his nose or his mouth, i've never seen him do it, just felt it on my hand. i keep him on a mulch i got from the pet store, spray him like once a day, temps are on the cool side around 75 F and hot side around 85-90 F. how can i tell if he actually does have one? what causes a respiratory infection? please help me!
