Do you let cats sleep in your bed?

I'd have a challenge keeping our cat OFF the bed at night. Even if I shut the door to the room she'd sit outside it and paw at the door, or squawk to be let it. She's an attention hog and not subtle about it. She tends to sleep right on or very close to my hubby or me, but we've never had a problem with hurting her in our sleep. About the biggest issue is losing bed space to a creature a fraction of my size and....this part is lovely....being SNEEZED on, in my face, in my sleep. I love her, but that's kind of gross! LOL
