I cluttered up the cage and changed the substrate. I added an extra hide, a log tunnel, and a bunch of fake plants. A smaller enclosure isn't really an option right now so I attempted to change up the enclosure. I guess I'm mainly concerned because I've always read if they lose 10% or more body weight that something is wrong with him/sick. He seems completely fine. He's alert, has a good grip, breathing fine, and has great sheds just no interest in food right now. He's always been a picky eater so I really wasn't concerned at first but this is the longest I've ever seen him go off food.
