This seems to be a controversial topic in most reptile places I hang out. Apparently a lot of people think live feeding of rodents is too cruel for snakes, turtles, etc. Along with the risks it presents with the rodents fighting back and taking a bite out of your beloved pet.
But few people look into the benefits of live feeding, despite it's cruelties. It depends on how you weigh out how you feel about the act in general.
I've read that live feeds have far more nutritional value, and on that basis alone it's a better idea.
I've also read that it enriches them by giving them the feeling of being the mighty predator that they are.
