*please answer if you are educated on reptiles or snakes* this is not school related but my ball python is kind of making a whistling noise when she breathes and im not sure if its normal to be able to hear her breathe or for the breathing to sound like that. Im concerned but I cant afford to go get it checked out especially if nothing is wrong. im a new pet snake owner and ill take any advice/information i can get (please only comment if you know what you are talking about)
