Context:
I inherited this gorgeous girl about 2 and a half/3 months ago from a friend who sadly died. She is roughly 2 years old. The friend was an alcoholic who allowed the cat to use the whole house as a toilet, despite having a litter tray. She is a very nervous cat who has only just begun settling properly.
She has full access to the outside at all times and a large, covered litter tray (came with her) that is kept clean (poo removed a few times a day and a complete clean every 2/3 days. I use expensive litter and provide a deep-ish layer.
She started out using the litter tray but has since decided that she prefers using the upstairs landing
. I really told her off the other day and she stopped for a couple of days but has since started again.
On the advice of a vet I use biological washing powder and hot water to clean the carpet to remove her scent.
I'm at the end of my tether! She does it overnight when the house is quiet. How can I stop her doing this?! I have nowhere to shut her overnight as the house is completely open plan (apart from bedrooms and she will toilet in those given half a chance and the bathroom which she can open the door to).
Help!!!
