So my dog has been joining me when I speed walk indoors from one end of the house to the other. She thinks it's a fun game so it's getting her activity level up too -- makes for a healthier dog. I had this idea that if I trailed a string behind me, our two cats might join in. Well, one wanted nothing to do with it. But the other is peaking at us from doorways as we pass by. Maybe in a few days, she'll join us.
