I'm actually in the midst of one right now. My Mexican Black Kingsnake female has been missing for 2 weeks today. Absolutely no sign of her. Got her at NARBC last month, and she's pretty small. Maybe 12-14in. The tub I had her in had too big of air holes. And my cats aren't being any help at all. Dang things...
Bummer... I know all too well how it feels. Best of luck, just keep on trying. All it takes is being in the right place at the right time.
