I've made this choice because i currently have 3 snakes, a cornsnake, an anerythristic boa and a ball python. My cornsnake is an adult and is set on adult mice around 3 inches big. My boa is just about 24 inches, and I tried feeding him an adult mouse and it was a success. My ball python is about 18 inches, I've been feeding her fuzzies but it doesn't show much of a lump at all. So I might just buy from rodentpro.com but I'm not sure how long my boa and ball python would stay on the adult mice, so I don't want to order to much and end up not using them. Can someone help and assist me in buying mice in bulk ?
