I grew up in Virginia and we never had heated bedrooms up there in those days so I have slept with my head under the covers all my life and still do. (Thank GOD for A/C!) I can't sleep until my face is covered even now but my kitties don't mind. They do know when the cover comes off Meowmies face, breakfast is COMING soon!... Now Giz, if I lay down on the sofa during the day and want a nap, she will come paw my head out from under the covers. By the time she is done, I am laughing so hard the nap is forgotten! Night time is OK with her but NOT during the day!
