I can see how you can say I said "feeding live will not give parasites". I never said it in those words but Ok. I guess I don't read what I type all that much. That is not what I meant. Mice breeding facilities are meant to be clean and disease free, but not all are like that. I did loose 2 snakes due to internal parasites, it was due to a bad mouse or the water dish was not changed when it should have been. My friends can only help me so much, in the end it was my bad.
Freezing does not garantee all parasites will die the eggs seem to survive, buy mice from a disease free facility. Over time a frozen mouse will loose nutrients.
Live food no, to much that can go wrong.
Pre-killed for those fussy eaters its the best way to go in my mind. As one pet owner to another.
