They really do. I wake up every day between 6 and 7:30 am because Bahloo wants to eat or play. No, he doesn't care what time I went to bed. No, he doesn't care how little sleep I've had or that this is the only day I can sleep in. He'll wake me up any number of ways...clawing at my feet, knocking a variety of items off my desk, crying in my ear, licking my face, attacking the underside of my bed, walking across various parts of my body, etc. And if I kick him outside, he'll sit under my window and howl. Yep, I've given up sleeping in.
