I like to wake up naturally. However, Harm won't let me sleep past his breakfast time. He has an inner clock that says "Feed Me" at 7:00 A.M. If I don't get up at the first bark, he pulls the covers off of me and jumps on the bed and sits on me with his face in mine. That is 85 or more pounds of dog on my chest!!! Of course, I get up and feed him and the rest of the gang. Then I sneak back to bed. ;)
Heh...animals are VERY insistant alarm clocks!
Luckily Halvah doesn't "go off" until I roll over for the first time. As soon as I do, though...she's on the bed chattering away, and doesn't take no for an answer.
It's bad if I wake up accidentally at four thirty or something, though.
