This does make me smile ;D It reminds me of my beagle I had as a child/teenager; who used to sleep in my bed!!! I could tell (when I woke up) how cold it was (no central heating) as it depended on whether she was on the bed and on top of or under the sheets. She would be very good at doing this without waking me up, but always managed to gain more than her fair share of bed space ::) I didn't mind too much as she was regularly bathed and she was a hot water bottle who never got cold ;D
