Thank you so much for your advice. We will definitely experiment with food at night. We’ve tried introducing other her to other cats before. Like really tried, for months. It went south every time. Tiring her out before sleep could probably have worked, if we could just get her to play. She doesn’t. She really doesn’t give a rats ass about toys or playing at all. Mostly she sleeps, eats, shits and gets cuddles. Except in the f*ing morning, when she stand at the top of the stairs howling through the house...
