I would love to do one with my cat! She would be constantly walking along the edge of my wide of the bed for a petting. Nothing like falling asleep and then hearing this loud purr at your nose. I'll stroke her head a couple of times, and then she'll turn around and lay down so I can stroke her tail. Then she'll repeat it. I usually fall asleep holding her tail.
Then she'll go on hubby's side of the bed to see if he's game. He's usually not, so she'll park herself right in between us. If we're spooning she'll just lay across my butt until I move. She's do damn heavy!
