Your first post made it sound like you knew that a large meal was a risky move. That's why you were checking to make sure it was "ok".
Why would you feed an animal prey that is too large for it on purpose?You were experimenting?
I can't imagine a snake sizes up what's offered to it if all it's ever gotten was an appropriately sized meal.
Snakes will eat something that's too large for them. Ever see the picture of the burmese snake that ripped in half when it tried eating an alligator? Yea...
Trust me when I say an animal that is twice the size of your snake is too big. Snakes have slow metabolism and don't need huge meals unless they will fast for months. Feed too much, and they can get fat, or will go off feed.
