So, kitties sleeping all over at odd places is normal behaviour. Hubby was just remarking about us having a fickle minded kitty. We can find him, inside our empty fish tank, on top of our copier machine, my book shelf, on top of our fish tank rack, all over the place that to me isn't at all comfortable. When you think he will settle in a place, and I try to make that place more comfy for him, he will use the place a couple of times, next thing you know, you won't find him there anymore, he had moved to another spot. I read that most cats dislike changes, but whenever I moved furniture around or add something new to that furniture, that's the place he will go investigate and settle in next. Ironic, the places I want him to be comfortable in, he won't stay put, the places I made up for myself, he takes over. He seemed to like new things, but only for a short period, he's fickle.
