I spent quite a bit of time looking on the net for what you described. Good thing my boss doesn't know.

Anyway I couldn't find anything that, that is native to North Carolina.
Best resources I found were http://www.mammalsociety.org/statelists/ncmammals.html and for all locations http://enature.com

There isn't anything that I could find that fit that description. I only checked native species to North America though. Could be something somebody smuggled in an let loose.
