i feed mine the same day of the week, at the same time as the previous feed. i know thats not necessary, but my ocd gets to me lol. anyway, some snakes wont eat before a shed, and i was recently surprised when i offered one of my mojaves a meal after he refused it 3 days before, and he took it. later on that night, he began to shed! so i suggest try what you want, but in the end, its all up to your snake. some take them, some dont.
