Dolly and the jumping Q

I heard a commotion in the kitchen this morning whilst I was in the shower, so I didn't check it out right away! I actually forgot about it, and when I did go through I found Q up on top of Melllvar's enclosure! I have absolutely no idea how she could have gotten up there, its around three feet high and there was nothing around for her to jump on, she must have jumped from the ground up! Q is definitely our brightest bun, she is good a figuring things out, but she obviously couldn't work out how to get back down safely, as she looked rather sheepish when I came through, naughty bun!
