Hi there, my boyfriend and I got a ball python at petsmart about 3 weeks ago. The pet store told us she was a picky eater but we got her anyways. She hasn't eaten since we got her and we noticed she hasn't pooped or peed either. We have tried to assist feed her but she hates it and tries to bite us. Her eyes are fogged and she is looking dull so we were thinking she is going into a shed but we are worried. Any helpful comments would be appreciated
