I sucks that your Nake has escaped. Snakes sure are good at it. DH has I think about 50 snakes at last count. All different ages. We recently lost a hatchling and found it. Look for warm places, like DVD players, behind the fridge, back of computer. I also accidently let 3 escape (all about 2 years old) when DH was OS last year and found all 3 still in the house. So you do have a chance. I hope he turns up soon.

You could also ring your local wires and fire station and leave them details. I know here where I live the firemen will come if they are not busy.
