Mine does that too. Can't work out whether she is bracing against both sides, or somehow manages to balance on the tiny lip between the wall and the lid. Cool moves though.
Hhhahahaha. Give her a small black sock and cut a hole in the toe end :D Then she'll be a full on Ninja!!

It definatly took me by suprise. I came in and first thought that she had escaped because i couldnt see her any where, then when i went to open the lid there she was, just chilling. I think i might get her to train me how to hang from ceilings, could come in handy at some point, lol
