We have a 4 month old ball python who is shedding for her 1st time in our care. she has shed twice previously before we bought her. She eats once every week and her temp stays at about 75 or 80 degrees and we keep her humidity anywhere between 40 & 60. Her eyes started getting milky and glazed over earlier this week and just yesterday morning they were completely glazed. We get home last night and her eyes are back to their normal color but she hasn't shed....is this normal?
