Your Sumatran is a Short Tail, not a Blood. Check out the three species here http://bloodpythons.com/cms/index.php/species-info
I have a 30lb female blood python that is near 6ft. She can pound a rat like a freight train. I would hate to have to move her to feed her because she knows by the smell of rat in the air that she is about to get food. I have never fed her anywhere but in her cage and she has never once even made a motion as if she was going to strike. She is very well mannered and a puppy dog in your lap. There is no reason to feed these snakes with their strong response to food in anything but their cage.
I also have three younger bloods that I had to tame down but even they are fed in their tub and always have been. I have never once been tagged by them in a feeding related way. The only times they have given me a bite is when they are being pissy about me disturbing them.
