should add both to poll. I feed F/T to all that will. Only one gets live, and only after going off F/T for a long time w/WEIGHT loss. Have another snake that refuses rats but destroys f/t mice at the tune of 6 or more a week. As a rule for me: allways f/t if possible, and allways the largest food up to 1 1/4 the snakes girth if possible.
