evan385 you have become a bit defensive, no body is trying to make you feel this way. The question is a valid one, and the reasons understandable. The point is figure all wild caught rodents carry parasites and figure that to be 100% certain all cysts and ovum are killed you need 30 days at 19.4ºF. That only leaves the possibility of other things aside from poison things like oils, antifreeze ect. Add virus into the mix and it becomes less certain again. These are good reasons why it is not a very good risk.

It looks like you will have 4 snakes soon? I'd suggest that it might be a good idea to check out the get many rodent breeders whom ship frozen rodents to you. It is likely you will save money and not be so reliant on a store for supply. Some of the large breeders claim a pinky rat is born every second of every day they have huge output and rarely if ever run out. This way you are only relining on your self to ensure you don't run out.
