Both of mine are allowed on the bed, and I never know they're there until I wake up and see them. In fact, even though I leave the bedroom door open so that Zelda and Mowgli can join me, half the time they snooze on the recliner. Until I hit the snooze button when the alarm goes off - then Mowgli comes to see me for snuggle time.

Just a quick warning! If you let your kitty on the bed, if she's feeling playful, she may spend a few minutes playing "pounce whatever moves under the covers" before she settles down to sleep. Fun little game, but it'll keep you awake as long as your kitty feels like playing. When my folks were cat-sitting Zelda for me back in June, they refused to let her on the bed. Well, apparently one night Dad got up for some reason, and she slipped into the bedroom. She probably would have gotten away with sleeping on the bed last night if Dad hadn't moved his hand under the covers when he'd gone back to bed. Because sure enough... POUNCE! Poor Zelda was promptly put out of the bedroom. So be ready for bedtime playfulness!
