Lily sleeps at the foot of the bed, and has never ventured up to the pillow . . . much to my chagrin. I would like nothing more than to have her cuddle next to my head, and I envy those furparents lucky enough to enjoy such comforting slumber. She also likes to sleep at the top of her cat tree. She never uses the lower perches except as a stairway to the top! Since her cat tree and litter box are at total opposite ends of the house from the bedroom, I have now put another litter box in the bedroom for her convenience as she is elderly, and to encourage her to sleep on the bed all night.
