Question?

Not trying to make this sound rude, but I'm just trying to offer some sound advice, so here goes: Whenever you feed a snake, especially ones that you'll be handling, it is always a very good idea to always take your snake out of the cage that it 'lives' in, and put him/her in a tub, box, or on a towel on the floor (my snakes notice that when I lay towel on the floor, it's feeding time!).
Which is why you need to feed them outside their cage, soon they will associate you opening the cage lid with feeding time, and in actuality you're just reaching in to take them out for handling, and they strike based on what they know/learned. For me anything to lessen the odds of getting bitten, is put to use, as I've been bit a few times, and it can be kind of startling...lol.

Cage aggression caused by feeding ball pythons inside their enclosures is a complete and total myth. They do not learn to associate their cages with food any more than they learn to associate a tub or towel with feeding time.

The feeding mode is triggered by scent, heat, and to a lesser degree, sight. Unless you smell like, have the heat signature of, and look like a rat, sticking your hand into your snakes cage to handle them will not engage them in feeding mode. Same with puting your snake in a tub or on a towel. They could care less where you put them down. You won't get a feeding response with out the proper stimuli.

There is no reason to feed a snake in a seperate location. In fact, there are quite a few very real reasons not to feed outside the enclosure.
