I just got this guy about 2 weeks ago from a trusted friend who used to breed. He is almost 3, and I feel like he's too small. I know that only maintenance feeding was done, so I know he isn't going to be as large as I'd like. I am just worried about his growth potential. I unfortunately don't have a weight right now, I have to replace my scale.
Does anyone have any thoughts? He's eating great, is healthy, just ... small.

This is him the week before I picked him up


This is him at home at his first feeding (he turned the mouse around)
