LOL, you're too lucky!
About 2 months ago Goldy, the big female, managed to get out of the 20 gallon they were in. I went frantic, thinking she'd burrowed into the substrate, then it occured to me she'd escaped. I had Monty and another big female in that same cage, with no weights, and they never got out. So I tore apart the entire bed room and found nothing. I searched three more times and then I felt hopeless. My bedroom is in the basement, and if it escaped the room she as a massive cluttered basement to hide in. So I search one my time, without hope, and find nothing. I go to the 20 gallon to hold my runt, when I see a little head poke out of a folder. When I searched I ruffled the folder pile and she came out. The folder was 2 feet away from the cage... And I tore my room apart. I also had my corn snake escape for a month, then 2 weeks, then a week and a half. Monty has never gotten out for more then 10 mins.
