He's been eating the same frozen thawed rats from the pet store close by since I got him. The maximum he went without eating was 2 weeks. Maybe because he's a pied, he's getting some white scales there. He used to have a black dot on his body and with time became 3 black dots like it's spreading. I'm glad it seems to be purely cosmetic and I can jokingly say he's graying out with age. xD
