How much does she weight? you know a hopper is a mouse, or are you asking if she can eat adult mice? feeding is all personally preference i feed all my snakes once a week doesn't matter if they weight 150 grams or 1600 grams. some people like to feed every 5 days until they hit ___ grams. seeing a bulge is not the best way to measure food IMHO. my albino is 700 grams and eats small rats(80 grams) and i do not see a bulge on her and it is in the 10-15% body weight.
