Don't give up. I was convinced when one of my snakes got out that she was under the baseboard in the kitchen. I ripped it all out and she wasn't there. She was in my closet across the apartment behind a piece of cardboard that was leaning against the wall.

Sneaky snakes are sneaky. She is somewhere!!
