I refuse to breed a female younger than 3 years old. No matter the weight at any age younger she will be 3 years old and atleast 1500 grams at that age.
I am one of those odd ones I only feed once a week nothing more and nothing less. I know a lot of people do feed more often and everything and thats great for them but I would prefer my snakes to live longer and have a better life. It is just an opinion but that's the way I feel. I have nothing against anyone who does any different, we each ahve our own ways. Mine just works best for me and I feel the snake gets the best care that way.
