Cold shoulder? No, cold ......!

I should have taken a picture but didn't think about it, instead I will describe how earlier today, my cat took up her usual position from which to survey her subjects, sat there a few minutes, decided that it was no morning for sitting about on a cold shed roof, promptly jumped down and came back indoors - leaving two small melted points in the frost and one, much larger perfect oval shape where her small furry posterior had also melted the frost!!
