I prefer to think of it as having an ever-present guardian angel hovering over me.
Since he lays with his head across my hips or stomach at night, I sleep like the dead, no matter what.

Sadly, I don’t let my Zeus on the bed anymore. Once he snapped at my husband when he was told to hop down. He had been up keeping me company (which I didn’t let him do often)and didn’t act appropriately when told he had to leave - we were floored by the snapping. Never allowed on the bed since.
He used to start out in a little ball at the bottom of the bed, and gradually would magically expand until he was lying stretched full length up the middle of the bed, and I would be shoved to the edge. I always felt perfectly safe.
