Just so you know, North American ratsnakes (corns, great plains rats etc.), are no longer classified as Elaphe, but are now Pantherophis. They are not really that closely related to eurasian ratsnakes, so you probably wouldn't have much success there either. I'm not trying to burst your bubble or anything, and you're more than welcome to try, but you'd be much more likey to be successful if you stuck to snakes that have a much more recent common ancestor. Just my humble opinion .
