Meet Ruby - also known as Ruby Sue - the runt of the litter. But whatever she lacks in size, she more than makes up for it in attitude. If she's not sleeping, she's moving. Even when she's nursing, she somehow manages to wiggle. It took me forever to get a picture of the little mouse because she wouldn't sit still. She's starting to walk (as you can see from her attempted escape below), and is already a little comedian.
