We are new in the snake world. We have a baby, 14 in and about the size of a pencil in diameter. We've been feeding 1 pinkie a week. He eats it fine, seems like the size is a max for his mouth. After about 1 hour, the lump from the pinkie is gone. He always has a bm by the next day. I don't know if I can move up in size, but is he getting enough to eat?
