Sleeping Comportment

I regularly sleep three, four, sometimes even five hours in a row at the beginning of the night. Too bad night starts at 8 PM. I went over six hours once last week, but the following night I ate every two hours just to keep Mom off balance. I'll be so disappointed when I'm too old to be this fickle. Then again, Sadie still wakes up four or five times a night sometimes, so I have a while.
