I know the weather hasn't been that warm, but I do find it more comfortable this time of the year to sleep with the fan on wafting a soft stream of cool air over the bed.
Last night I woke up so tightly pinned down by the cats enjoying themselves stretched out down either side of my legs, I had cramp!
I might have to turn it up a notch tonight. At least Jasper used to crash out on his back, legs akimbo, at the bottom of the bed.
