We just went to feed all the snakes and when we went to feed our Kingsnake found out he wasn't in his tank. We searched the room, but didn't find him. We had just recently moved him to a new tank (2 weeks ago) and didn't check to see if there were any gaps between the lid and the tank and sure enough, after finding him gone, we found a small gap he probably slipped through.

So we suspect he's been gone for about a week to a week and a half. Is there any way of finding him again or luring him out of hiding. There is a vent in the floor about 5-6 feet from his cage and I'm worried he may have gone into it.

Any advice?
