He is eating a large weanling every 10 days. The pic makes him seem thicker then he actually is I guess, he's roughly 1.5 inches in diameter, I don't know what the norm is but I have not powerfed, and the snake has extremely strong (as in not inbred at all and good sized parents and grandparents) genetics so he may be on the larger side because of that. And his borth date is late March...I believe the 27th..of '04 so he is a little under 9 months in actuality.
Thanks for the comments!
