Ok so I just got an adult proven breeder spider ball python from a breeder. I notice he has stuck eye caps. I am not worried about the eye caps but he has a whistle once in a while when he breathes. It isn't every time but if he gets excited I can hear it more. He has no discharge and I checked his gums and no bubbles or anything abnormal. Is this just from a dry shed? I have had him for a week. I just noticed tonight after the rat freaked him out (he didn't eat). He was really upset after that so I heard the whistle.
