I was laying in bed last night, having just stopped reading and turned out the light. I felt a cat jump gently onto the bed, walk across me and then down into the hollow between me and my husband. Having been convinced all "lurkers" had been put into the kitchen, I sat up and said to K, "I thought you said all the cats were downstairs - yet one's just walked over me." I put my hand out to see who it was - and there was nothing there . . . He hadn't felt anything (well, I suppose he wouldn't, it was me that was walked across). I can only assume it was a little ghost cat, visiting, and giving it some thought, I think it must have been my darling Lucky, as the strides were very short (she was a little short-legged cat). Bless her - coming back to say hello.
My eldest daughter has spoken of a ghost cat on her bed before now too.
I am sure the pragmatic amongst you will think - daft woman, it was just her imagination, but I am sure the animal-lovers may think differently . . .
