'D&D' think I do that because I am glad that they have returned home. But to be honest, I do that so that they will think I'm cute (which I am), and feed me.
There is only a few bad points about rolling about the kitchen floor.
Number 1. It cause my fur to create static electricity, which can not only shock 'D&D' (which is funny!), but also shock myself if I brush up against anything meta.
Number 2. Heaven forbid, if the floor is just a tad bit dirty (tracked in from outside), I tend to get my fur a wee bit dirty.
Number 3. Ummmm sometimes the floor smells like feet.
Well, a rolling kitty, gathers no moss!
