I have a male BCI who I got as a rescue, his living conditions were deplorable with the prev. owner and they were not feeding him but 1 pinky a month. He is 1 and a half about now or over, and sits at just under 4 foot, I am wondering, is it possible his prev. owners could have stunted his growth? It seems as though he should be bigger, but them again, I could be wrong. Whats your boas average size at this age?
