This sounds more like your cat is trying to tell you not to leave her at home. My cat was doing the same thing.. my grandmother died (I lived with her) and so we painted the place, moved all the furniture, and I even left her for a week while we travelled to Saskatchewan for the funeral. She started peeing in my laundry baskets and any pile of clothing (if it had been worn) that was on the floor. She had also done this in my grandma's laundry baskets. I took her to the vet and they said that Bassett was upset with the changes in the house and was likely lonely during the day (she was used to having granny around). She gave me an antidepressant that was also supposed to stop wierd urination called Apo-Amitriptyline (10mg/pill). All it did was make her sleepy the first two days. I also made sure to make extra time for her and pay close attention to when she was alone. Also, I ended up getting another cat for her to play with during the day. She only took the pills every day for a week, then every second day for a week, then once a week for three weeks and she was totally fine. She hasn't needed one for a while now and is using the litter box normally. I know that drugs are a last resort but this seemed to work really well for her, and my vet said it's a very mild pill and dosage. It's always the first one they try and have like a 90% sucess rate. You might want to look into it. Is that couch a place where you like to sit? Or a place where you would keep your work/school bag? She may just be trying to tell you something.. especially if she is peeing in your shoes.. Anyway, good luck and I hope everything works out.
