If you want to breed, I've heard you're supposed to have around 500 grams per foot. Please correct me if I'm wrong, because I just got this information off of a website.
As for feeding, you could try many things. Feeding live, feeding gerbils/rats/mice/hamsters/chicks, changing the gender of prey, pre-killing (Expose the brain), raising or dropping temperatures, putting them in a dark place before feed, making the mice if F/T do a dance, separating when feeding, etc.
Side note, when feeding live please stun the prey by bumping it against something and use tweezers if the prey item looks as though it could harm your snake.
Those are just some ideas, hope that helps.![]()
