I've had my ball python for about a month now. She is around 6 months old. She ate for me the first week that I had her, which was only 4 days after I brought her home (I left her alone until then, and for a week afterward). She hasn't eaten since then, so for 3 weeks, it will be 4 weeks on Sunday if she does not eat again. She has no signs of illness and her enclosure is at the proper temperature and humidity (about 83 on the warm side, 76 on the cooler side, humidity stays at around 40-60%). She is located in my bedroom where I spend most of my time, but I have her in my closet behind a closed door. Even so, I don't make much noise that she should be stressed by my presence. She is active, she's rarely balled up and doesn't often go into her hides. In fact, since I've had her, I've only seen her in there once. She is climbing at night, and definitely is not lethargic. There doesn't seem to be anything wrong but she still isn't eating. I think she may soon be going into shed, but I haven't seen that yet so I'm not quite sure how to tell. Sometimes her belly looks pinkish, sometimes it doesn't. Her skin does look a little loose at times, like it's wrinkly, but not around the neck area which I've been told is a sign of dehydration. I haven't noticed her eyes looking cloudy though, and her colors aren't really dull. I posted here before about how she isn't eating and people told me to look for signs of weight loss. Other than actually weighing her on a scale (which I don't have yet), what should I be looking for? How long can she go on without eating at only 6 months old? It has only been a month but should I be worried?
