K, here's my story. A kid I used to know from back in highschool caught a live mouse that was running around one of his kitchen drawers and got tangled in a cheesecloth bag. He thought it'd be smart to feed the mouse to his kingsnake thinking his 3 ft king should take the mouse down alive no problem. 2 seconds after he introduced the mouse into the king's enclosure, the mouse attacks the king, 5 minutes later of trying to separate the mouse from the king's neck, the king bites the kid, coils his hand and starts to constrict the kid's wrist while the mouse is furiously biting into the king's neck. 15 minutes later, after some help we separated them, I managed to kill the mouse via cervical dislocation (while still attached to the king, which promptly leg go), but the king suffered a deep spinal injury and died later that night. SO, moral of the story, do not feed live wild mice to your snakes as they are bloody vicious little things.
Second story. The same kid, has his redtailed boa escape on him. Mr. Redtail shows up 2 months later in the laundry hamper particularly full looking. Turns out he raided a mouse nest (after necropsy), because it died a couple days later due to some strange GI tract infection (swollen, purple, bleeding stomach and intestines?). Its last meal consisted of one rather plump (probably pregnant) mouse and two smaller mice. So, do not feed wild mice to your snakes period. Even if you prekilled and froze them for a time, it probably won't kill all the bacteria, fungi, virii, or any other organisms that may harm your snake. Microwaving is not an option since that would cook the mouse. Gamma irradiation is expensive, dangerous, and turns the mouse insides pulpy. So, no easy way to do it, just steer clear away from wild mice.
I hope you reconsider.
