I feed no matter what.He has eaten in blue and on the same day as he shed . In fact he went blue last thursday and I feed him on fri as usual and then he shed yesterday and I feed him again I was not sure when he went in to shed the first time but I felt bad makeing him wait if he was hungry and would eat so I tried anyway and he went for it . So this time I went a head and offered agin and the same was true so I guess its worth a try if u want .
