green poop

Hello! My leopard gecko George hasn’t eaten in a couple of weeks- which by itself doesn’t concern me. He shed last week, on Friday, and he’s pooped a lot since then which is weird because he hasn’t eaten anything. And they all have been green? I’ve noticed the last 2 times the pee was the green...

My leopard gecko has not eaten for almost 4 weeks and every time I offer food she runs the other way. She is still active but recently has been having green feces. I don't know what to do and would really appreciate any help I can get.
