@ian I have the same problem with sleeping spots -- I have a wide variety of cat beds (one heated!), but the best feline sleeping spots are still the geometric middle of my bed and that piece of cardboard I've been meaning to pick up off the kitchen floor.
@ian Our kitty Ripley likes ponytail holders and these teensy lightweight balls, possibly for the same reason: she can carry them in her mouth and drop them on our faces while we attempt to sleep. https://www.amazon.com/dp/B01C2NLVBY/
