You've heard from me on this topic before
My comments on this are quick and simple but I thought I'd chime in since I'm in the 10% of people who do feed live (that's rounding).
I have fed live since mine was a hatchling. It is on six months now and feeds two live fuzzies every seven days no prob. The snake attacks immediately and constricts until the mouse is dead. I do watch the viv and make sure it dies just as Chibitamalove had said he does.
I do realize fuzzies are small and can't cause significant damage. Fine. Maybe as the prey increases yes I understand what could happen.
However, on that thought. Snakes are adaptive in captivity as well as in nature. If taught from the beginning to feed live and they kill effectively then I don't see a problem. I know friends that have had boa's and fed live for years with no repurcussions. Lucky? Maybe... but I believe it can be done so long as you don't start off with thawed or pre-killed.
Also, for those of you who say your passionate about mice. I don't have it in me to pick up mice from my pet store, come home, and slam them against a wall or suffocate them, or kill them in any way. Yes it may be easy, but that itself is cruel. At least when I feed the mice to the snake, I know that that is just the course of nature and the food chain itself in action.
My pet stores around here only sell live unless I'm lucky and petco has some pinkies that are frozen. But they do not have anything above the size of fuzzies that are frozen. So therefore what do I do when it comes time to feed larger prey? Those of us who feed live may not have many options and have our reasons for doing it this way. While this is a heated topic I think we all do need to respect how we each go about doing things. I feel like some people who have taken a very heavy stand almost talk down to those of us who feed live, and that isn't really too cool. Like I said I respect those who go about and started feeding off thawed, prekilled, etc. I just think those of us who do not, should not have to feel like we are ultimately hurting our snakes in the end. We all feel like we take very good care of our snakes and would never hurt them or put them in harms way.
My two cents...
