i dont feed live, for the main part it is illegal in my country unless the snake will not eat anything else and its life is in danger if not fed live prey. but i have done in the past when i thought it was nescesary with non feeders. i would feed them all live if it were legal. 80% of what i feed is prekilled by me at the time i feed them the other 20% is frozen/thwed.

when i have fed live ive watched the snake and the prey intently untill it has fully killed it and there have been a couple of times when ive had to use my tweezers to stop the rat from biting the snake. i would never leave a rat or mouse unnatended with any of my snakes its not worth the risk
