Getting bit doesn sound very likely. Why else shouldn I feed live prey?
Mice and Rats often carry internal parasites that are lethal to snakes if not killed properly. It’s very common for a young Boa to die from parasites just because the owner was reckless and careless enough to not take all precautions before feeding. Young Boas in captivity do not have the immune system to battle internal parasites, and it usually results in severe sickness or death. Prey should ALWAYS be killed and frozen (if possible) before being offered. Of course, frozen prey should also be thawed before being offered, and is the best method to use.
