I'm remembering a few years back when we had a genuinely cold winter and the thermostat was on the fritz so the heating kept going off. And also at one point there was an ice storm that caused a power outage for a few hours one morning around Xmas. So I slept with my door open to allow the cats to come sleep around me -- and yes, though they tend to fight they used me as a DMZ and there was less squabbling than there might have been. Generally it would be Ju-Ju lying along my left size and Dizzy down on my right against my feet (once he'd gotten a few cuddles out of his system by parking at my head when we first settled down), occasionally Chooch or Squeaky would come visit and I might wake to find a cat between my shins and one to either side of me.

Last winter it never really got cold enough to need the additional warmth, or maybe I just shut Dizzy into my room with me a night or two. Have to see if we get a proper winter this year -- no idea what it'll do to have added the kittens to the mix if I wind up sleeping with the door open again.
