Just discovered she has weed in an empty plastic tray under the stairs - at least she is trying to do it in an okay place. She is 17, has several illnesses but to me still has quality of life as she still plays and is clever enough to hide behind the sofa when she has sneaked back in or make me move stuff off the bed so she can sleep in the sun. She has been weeing in the wrong places for several weeks now. She has access to a big garden and hasn't had a litter tray for years except for when she had to be kept in, but she doesn't like them.
