My male yellow is only 6-7 months old and roughly 4ft long. I was feeding him small rats every 7 days and hes been growing so fast i recently bumped him up to medium rats every 7 days. Hes getting big but i want to make sure its a healthy big and not an overfed big. How often do you feed your greens or yellows? Include the age of the snake and maybe list the time period you waited to bump up prey size.
