I have done both with my short tails. When I just had one I would always feed out of cage. He was alot calmer when trying to be picked up then, but he's gotten to be such an aggressive feeder that its hard to pick him up to put him back in his cage after feeding. And hes so large that the only place to do it is the bathtub.. and I cant leave him in there to get off feeding mode. Anyways I would say it doesnt really matter that much as long as you handle them frequently, you will probably be taking equal chances at being bitten. Tho the specific animal I'm talking about has never even struck at me aside from during feeding, and I've had him over three years.
