I have found that feeding multiple smaller meals weekly keeps them eating more consistently than feeding large meals.
2 meals a week equaling about 15% of body weight to growing snakes and 2 meals equaling about 10% of weight for adult snakes.

I never feed jumbos to any ball pythons, especially males but even females only get fed smalls or mediums when they are adults.
Feed them too large and watch them go on crazy month long refusals, not any more...
