It's up to you. I have three set days I feed most of mine (Sunday, Monday, and Wednesday), and have a couple who are on a 5 and 10 day so their feeding day switches. I just have the week eaters on three separate feed days so I'm not feeding 10+ snakes on one day! That's a lot of thawing, heating up, offering, etc since some I really need to play with for them to take their food.
