Wow. Yeah. I second that. I think you did something wrong in your math to come up with 100g for that little cutie. How much does he weight? As a helpful idea some recommend 10 - 15% of body weight of the snake. So take the weight of snake X .10 and weight of snake X .15 and feed something weighting in that vicinity. Also going by the girth as Deborah states. Your snake would have to be 1000g or so to need a meal that size.
Yes sorry it is 10-16 g. I was using my phone and it auto-corrected to 100. This is the chart I was referring to...
