I'm glad you found your escapee so quickly.
I've had 4 snake escapes.
1.) My butter got out the night I brought my cat home. I found her a week later under my kitchen sink.
2.) My cinny got out and I found her 10 minutes later at the bottom of the snake rack.
3.) My pastel ph hypo got out and I found him on top of my cinny's tub (so he didn't make it far, they are right next to each other).
4.) My pastel ph hypo got out a second time and I found him at the bottom of the snake rack.
After the last escape I fixed the rack and haven't had an escape since.
