A mouse bite with no blood is probably something you're going to have a very hard time finding on your snake if you don't know exactly where it was bitten.

Sounds more like a "non-event" to me. I feed live every week to all my crew, in fact, I've always fed live, going on four years now.

They're very adept at dispatching their prey and their scales are part of their protection.

I'm sure your snake is fine.
