You have some great looking snakes, I am very drawn to the pewter and cinnamon. As for the cinnamon being a bad eater, you could try live if you are not doing so. Ask who you got her from what they were feeding, some ball pythons can be very picky as to whether they will eat mice or rats. If you are not currently, try adding some nice tight fitting hides, even if you have a rack system, sometimes it does make a difference.
