Oh lol Marti, don't scare your Mum like that
They are very fast little things, I'm always amazed at how much ground they can cover in a short space of time lol. I was busy cleaning their water bottles one day and Boris was safely (so I thought in his playpen). I was going between the bathroom and the hamster room when out of the corner of my eye I seen Boris running across the room back to his playpen! He's done that a couple of times to me now, the other time he was in something I was positive he couldn't climb out but he did! Now I don't take my eyes of him for a second lol.
Glad Marti was ok after her adventure, though I expect she will be looking for more now she's got the taste for it
