I haven't lost a snake yet, but I have had a leo escape on me. Took about a week to find him. He was behind my guitar amp and he ran out when I started playing. He could honestly be anywhere at this point but from what I've observed he will likely be someplace warm. Definitely keep the UTH out with a hide and check it often, he will show up eventually. Helped a friend who lost his corn snake before, he was found on the carpet basking in the sunlight by the window. Good luck!
