He eats rats I buy from a petshop where I'm from that are marked as medium, but some are easy larges on RP. He takes them down no problem. His largest circumference is 8 3/4 inches, I did also feed him 2 days ago.
I was wondering because he is actually very active, and explores like crazy when he is out of his tub. I handle him every day, and give him a good soak or two per week.
