He's ornery 'cause you changed his diet! Just kidding. I think I recall hearing that the westerns are a lot more likely to take mice than the easterns. No idea why. I was never one to try to change a snake's diet. If I had a local snake that I could not supply with food, I'd cut it loose. I actually did pretty well with corals for several years. Try keeping them supplied with food! Cemophora are a bear. ~~Greg~~
