I usually wake up around 4:00 am to go to the bathroom. I then go back to bed and sleep until about 6:30 when I really get up. Unfortunately, over the past week or so my getting up has stimulated Zane to start yowling. He doesn't want me to pet or play with him, for he ignores/resists when I try, but he won't let me go back to sleep--as soon as I start to doze off he'll start up again. He has a very penetrating yowl; if I shut him in another room, I can still hear him. Also, I live in a duplex, and I'm afraid he may be disturbing the people in the other apartment (they haven't said anything, but they may just be being polite.)
