Wild Mice?

[Bighead]

I am assuming the answer is no here, but thought I'd check just in case.

I live way out in the woods on Mt. Baker in Washington. A couple nights ago I thought I saw something run along a wall out of the corner of my eye. I didn't see anything when I went to investigate, but decided to set some mouse traps and see what happens. Since then I've caught 4 adult mice. Is there any chance that these would be safe to feed my snakes after I freeze them? It would save me quite a few bucks.

My other question is, has anybody seen plans on how to build a cheap "live catch" mouse trap? I'd rather just relocate the little buggers than brake their necks. Thanks.
