If you buy your feeders, feed them and give them water prior to feeding (allow 2 to 4 hours before feeding them off)
Have a strong routine feed the same day each week.
Leave the rodents nearby your snake enclosure, scenting will entice the snake to eat and will allow you to do the above if necessary.
Know your snake and watch is body language, not need to offer food to an animal that is obviously not interested
Do not feed an oversize prey item even the LARGEST BP (3000 grams and up) does not need anything bigger than a small/medium rat. Adult male will do well with a small rat.
Do not stress the prey, do not taze or knock out the the prey. There is nothing more dangerous than an animal comming that is coming out of a daze and is disoriented.
Feed your snake inside it's enclosure, monitor feeding and remove the prey if not eaten within 10 min.
Do not leave a prey unattended.
