So about three weeks ago I picked him up from an exotic shop in the area and she was really tiny, so I started him on f/t pinkies every 4-5 days. Well now he has gotten longer not really thicker but when i feed him the pinkies there isnt really a lump in his belly like there was before. I've tried to give him a second pinkie but he was not interested in it but still seemed to be hunting for hours. Should I try to bump him up to a fuzzy? They seem so big but due to his length I'm not sure. I'm new to the Colubrid world lol

Thanks!
