By getting a corn snake for a pet, you're taking a lot of the wild out of the corn. Is keeping a snake in a glass tank with an artificial heat source "natural?" Is it "natural" for it to always have good, fresh food of the right size and clean water always available to it? Is it "natural" for it to be taken out of the tank and held by a person?
You feed live mice so that your snakes will know what to do if they get outside? They can get outside that easily? Maybe you need a more secure place for your corn. Snakes don't lose their instincts just because they don't have a live mouse to battle. Sounds to me like a weak excuse to see something "cool" every once in a while.
Physically killing them and freezing them is wrong? Well, then, letting a mouse be slowly killed in a painful way is perfectly all right then, huh?
If you can't bring yourself to kill the mouse you could ask someone else to do it. If only you'd read through some of the older threads here, you'd find alternatives to bopping your mice.
You think feeding your snakes as they would in nature is good for them? What happens when the mice chomps down on your snake and leaves a wide open, bleeding gash? Or bites an eye off? Oh yes, it must be all fine and dandy because they kill live mice in nature, right?
I don't know how old you are but judging from the way you type and spell, I don't think you're very old. For all I know, you could be a little kid who doesn't know any better. Whatever. It doesn't matter. What I'm trying to say is, if you truly cared for your snakes you would be willing to overcome obstacles to help them. If you really had your snake's health and well-being in mind, you wouldn't purposely endanger it by doing something that you know is potentially dangerous to it.
And if you don't have that as your first priority, maybe you shouldn't have any snakes at all.
