problem feeder!?

[Matt]

first off, let me say that i know this isnt a big deal, Im not worried, but i am a little frusterated.

My small Southern Copperhead has refused her last 4 meals...before this she was a great feeder, but about a month ago, she refused every meal since.

Just wondering, if anyone has had any good experiences getting these guys to eat. Ive tried mice and rats, live and dead, she is still really active, but doesnt seem to persue any food.

I also know she could be naturally going off food for the winter, but it is pretty late in the season for that

Anyways, any previous experiences would help!
thanks
