I'm not big on stunning live prey. I figure if the snake can't handle it's prey live then you should be feeding frozen/thawed or pre-killed. Most healthy snakes can handle an appropriately sized live prey animal, though f/t and p/k are both perfectly good methods of feeding. Stunning is to me a bit inhumane to the prey animal. As well if it suddenly comes to, you've got a disoriented, hurting animal in there with your snake. That is just not what you want to be doing really to either of them during a feeding.

As far as where to get live prey.....where'd you get the snake? If they were feeding live prey, are they local and can sell you some? Some pet stores sell live feeder mice and do a good job of it, some do a horrible job of it or only sell pet mice. This is something you should have looked into before getting the snake but that being said, now the best you can do is quickly find a good supplier that will sell you top quality mice.

Feeding live safely is not about "just throwing the mouse in". You need to make sure the snake is used to eating that particular size live, that the snake is awake, aware and ready to hunt, that the live prey animal is itself fully hydrated and well fed and not particularily freaked out. Introduce the live prey as far as possible from the snake so your snake has a chance to set up it's strike safely. Stay close but don't hover over or you'll distract/put your snake off it's hunt. If the prey animal isn't taken within 15 or 20 minutes, remove it, feed/water/house it appropriately and wait for next week.

If you feed live you will have the occasional refusal so you need to plan ahead and have supplies on hand to house the rat or mouse until the next week's feeding attempt.

Melissa, you can't stun a rodent then expect to have it recover and save it for next week...that's cruel dear. Also I wouldn't suggest you switch methods of feeding week to week or types of prey. That will throw off your snake and only encourage it to refuse to eat for you. Ball pythons are creatures of habit and routine, they like what they like when they like it....change that up to much and they will simply refuse to deal with food, you or much of anything.
