Shedding again?

Hello,

I have my ball python now for one and a half months. He is 3 years old. Since he is with me, he shed successfully on 14.1. this year. His behavior got weird few days ago, he is calm and not moving around as he used to do normally. Today I noticed his color is changing and eyes are looking grey, as it will be shedding again. Should that worry me? Is this normal?
I have to mention too, that since he is with me, he didn't eat yet, his last meal was one day before i got him, that was on 30.12.

Well, if 14.1 means January 14th then that is pretty normal. They will shed about every month - 3 months. Sometimes less if they aren't growing much.

The not eating is a little concerning though. What is his enclosure like? What kind of thermometers are you using? If you post a picture of your setup, we might be able to figure out why he isn't eating and get things straightened out for you.
