I guess I worded the question wrong. I know they get big. I have burmese pythons and female red tail boas so I can care for a big snake. I guess what I'm trying to say is how do would I go upon feeding it modestly to where it's getting the amount of food it needs but not to where it will hit 16 feet in its first year (I'm exaggerating of course). I didn't mean to sound like I didn't know what I was talking about in the first post. I guess I just didn't word it properly.
