Thank you Marion for your lovely reply. I enjoyed reading about how your four act upstairs. Kitty has not quite got that far yet, but when I turn the lights out she comes up and puts her nose to mine to check me out before going to her own. She has not yet tried to join me on my bed, but loves stealing things from it given half the chance! I also have to be careful to hang my clothes out of reach or she will collect them and take them to bed with her.
