For a little comparison/perceptive the best eater of my corns I got the end of may in 17. At the time he was about 11 or 12 inches and under 15g. So he is probably about a year old now. Currently he is 170g, up to 35" and eating medium adult mice. Another corn that I rescued was a 2yo his previous owner was only feeding him a fuzzy. He was about 22" and only 70g. After a couple of months of slowly working him up to the hoppers level he is about 120g and almost ready to move up to small mice. Once he gets up to feeding on mice like he should be his feedings will get cut back.
