My baby boy

My 9 yr old male normal ball python has developed a pinkish tint to his underbelly. He doesnt seem to be in pain and is just fine being handled but he did refuse to eat this week. I was just hoping someone could shed some light on this. Is he sick?

Pinkish belly normally means going into shed. No need to worry

Thanks. Ive had this guy for over a year and ive never seen it get this noticeable. He is going into shed cuz his eyes are gettin pretty smokey.
