feeding: inside or outside of cage?

[Reticsrule]

i had always read that it was best to feed outside of the snakes cage so that when you went to handle the snake, it wouldnt mistake your hand for food. it seemed logical so thats what i have been doing since ive had my boa. then the other day i read somewhere that it is pointless to feed a snake outside of its cage and has no effect on whether or not they will bite you when you go to handle them. then i got to thinking about it and if you fed the snake inside the cage it would be easier(considering youre using newspaper as a substrate) because you wouldnt have to move the snake into a feeding container which may be hard if you are dealing with a large snake. so what do you guys think, is it better to feed inside or outside of the cage?
