My snake weighs 177 grams. He has been eating two hoppers once a week (and I usually alternate one week two and the next one) but I just went up a size to mice weighing 19 grams. Do you guys go by the 10% of body weight rule or 15%? 10% would mean the mouse is somewhere around 17 grams and 15% is somewhere around 26 I think? These numbers aren't anywhere close to one another so opinions would be appreciated!
