The proper way to feed live is by setting the rodent on the side of the enclosure the snake is not on.....then watch until the rodent is constricted.

By "throwing it infront of her", you are probably just causing the snake to become scared and intimidated by its food. Ball pythons are ambush preditors....put the food in and let it go toward the snake.

Using hemostats, tongs or any other object to hold any live rodent in the air for feeding is inhumane and unsafe. By doing this, you are creating alot of stress in the rodent. If you feed like this you will have a much greater chance of the rodent attacking your snake. I would suggest only feeding this way with p/k or f/t rodents.
