I knew I'd seen a thread about this somewhere!
Have recently realised Cloud is far more of a keep me cool cat than otherwise. She doesn't really seem to be inclined towards areas which would give her extra warmth, be they cat beds of similar. Only exceptions to that would be my dressing gown, or sleeping on me at night - and even at that I'm convinced that heat is one of the things which means she'll move off.
Recently, with the warmer weather, I've noticed that she's more of a tendency to go out into the hall, bathroom or even down to the front door (coldest spot in the house) if I've got the heating on.
I did wonder at first if it was a sign she was more ready to think about exploring the world outside, but she still shows nervousness when I open the door - and when things come through the door (aka the posty delivers something). Then I noticed the cool breeze there.
She wasn't in the lounge at all this morning, but now I've turned the heating off and it's not so warm, she's asleep up on top of one of the couches.
She does luxuriate in sun patches when we get them, but that's pretty well it when it comes to heat seeking...
