Fearnot,

I would tell you to be patient. This has happened to me before.

Back in 2008, my now almost 5 year old alterna got out. Pissed off and disappointed, a couple of days went by and one of my female visitors was "surprised" to see a gray,orange and black snake going under the couch.

I have had 3 snakes get out of my enclosures. Each time, I found all 3 snakes after a day or two. My advice to you, be patient, try and search at night time. As long as your doors and windows are secure, she will pop up.

Good luck man.
