Lost Male Tabby Cat Lilburn

I've lost my sweet cat. His name is Riggins. Grey tabby, 2 years old, male. Was last seen Wednesday afternoon, December 3rd. I live on acreage off Oleander Drive in Lilburn, but the property backs up to a creek that connects to neighborhoods off Five Forks Trickum and Killian Hill. He's really only friendly to me, so I kind of doubt he would let someone else catch him or just go to another house.  770 605 7045
