You know, I purchase these cages that come with their own lid and the lid slides in and locks in place and there's even a place at the very front that you can put a lock to REALLY prevent an escape. After using these enclosures, NONE of my snakes have EVER gotten out. You can get them at Petsmart or Petco. I've never used a lock on any of the cages, because the cage is just awesome!
I think your mom may have possibly just captured your snake. Well.. unless there are local Milk snakes slithering around your neighborhood then that may not be your snake, but there's a good chance she found him!
roflmfao.......
goodluck!
