No guarantee on anything. If you had his snakes they may have done better, or worse for you and vice versa.

I feed my sub-adult/adult girls every 5 days... small rat. One has doubled in weight, one has only gained 200g- most others are inbetween. My Pinstripe is a HOG!!

My hatchlings never refuse pups. I have a 1.0 normal that is ~100g and a 0.1 butter that is ~200g. They were fed on the same schedule.... go figure. That's the extreme example. Most other 2012 recent hatchling pick-ups are 150- 160g after a few feedings.
