I found this interesting. Our local mom and pop store raise, and freeze, their own prey supply for the store - which I love btw. While trying to determine the proper prey size for our '09 bp the prey breeder, and snake owner, guy says that he goes by prey skull width compared to the width of the snake's jaw. He said that when choosing you want to feed nothing with a skull wider that the snake's jaw. I found this interesting. Both weight and width seem to be hard way to go because your snake could be either a) overweight or b) underweight and this could lead to an improper prey size. What do you think about this?
