I have an expen like that one you have and my little houdini is probably the first to break into jail and not out.
I was having some people over and I didn't want to risk her getting outside as people would be coming in and out so I put her in the expen in my bedroom. Well little Miss Thang decided she want to come downstairs and so she she did. She jumped over the top and came downstairs. I saw her just as she was going back upstairs. When I got upstairs to check on her, she had jumped back in her expen (either that or she closed the door behind her). I had to close the bedroom door.
