Yes that was what i thought also, but the seller is a experienced ball python breeder and what he said is the rat is not thicker then where the snake is biggest. And it could be 1- 1/2 as big as the snake, the rat is not thicker then where the snake is biggest, but the weight of 330g and a meal of 75g sounds strange anyway. If i get rats that is 36g then the rat is way smaller vs the snake.. But in weight difference og sounds mutch more right.
