Unsettled

Lulu is feeling a bit unsettled. How do I know this, you ask? Because she is wandering from room to room. She knows that I normally go to bed around now, but things are all topsy turvy with Gus gone. She's come into the room and gone into the closet a few times. Even though she's only had a couple of accidents in the house, mostly when I'm not paying attention, I'm always paranoid that she's going to pee. So I say to her "whatcha doin', Luli?". How does she respond? By laying down and licking the carpet.
