At 383 grams I would make sure that rat is of appropriate size...It might be too big, so she might be shying away from it. Could be the season like someone else said, and my one male is on and off with food right now. 2 weeks is really nothing to be worried about, so don't panic. My one male went off for 5 months, and then one day he decided he was hungry again. Try offering a smaller meal, and see what happens. Also try f.t, its a lot safer for your snake.
