The most accepted feeding guide I've seen has been in this thread:

I like that it does say to monitor your individual snakes needs underneath. It's true and a good blurb.
But I feel that using the 10-14 days as a guideline starting at that 350 gram mark can lead to some underfeeding over time. Even following that straight up into the 3500 range.
As it said, every snake is different. And if mine are on shed, sure they get fussy on food. But if I fed my big gal a medium rat 1x a month, she would not be happy. She starts pushing at her walls at the end of week 2.
I would more follow those guidelines weekly...And if refused, then understand the needs are different for some snakes.
