IF you knew anything about raising these animals with their full potential, you'd know that eventually, the snake will stop being interested every 3 days, 4 days, 5 days, as they grow, until they aren't really interested in food more than once a week usually - an exception being putting weight on back on females after eggs.
This second post you made is just downright ignorant.
1. You're claiming that these snakes will literally KILL THEMSELVES by making the choice to over eat? Do you even own a ball python? Show me 1 well documented instance of this, please, show me.
2. Comparing essentially the most natural diet a python could possibly have, with the horror of the "food" they sell at McDonalds is absolutely ludicrous. Do you understand to any degree what homo sapiens are supposed to be eating? McDonald's is not food. Not real food. Human beings were never designed to be eating the things they sell at these restaurants.
