I have two cats (siblings / litter mates). For years they were house cats in my flat, but we now live in a house and they have access to the outside.
We still use litter trays, because they are used to them. We have two of the covered ones and two open ones in 4 different rooms. These are scooped daily and totally replaced every 3 days.
One of my cats will not stop peeing on the carpet. This never used to be an issue for her, but over the last year it has been almost daily. It started with her peeing on the letters that were posted through the letter box - I think she found this stressful and peed to mark her territory. We put a basket on the door to catch the letters but the peeing continued. We eventually replaced the hall carpet with laminate because despite daily cleaning it smelled terrible. That put a stop to it.
But now she has started peeing on the living room carpet - the same place, three times in three days. I've put a litter tray down on that spot, but I am worried she is just going to pick a new place.
She's been checked by the vet who says there is nothing physically wrong with her, and it's probably just a habit.
Any ideas on how to break it? At the moment when we are out I am keeping her shut in the kitchen / dining / utility because they all have hard floors (she can still get outside) but it's not a huge space and it means she can't get to her favourite hidey holes upstairs.
I don't know what to do because I really can't afford to replace the sitting room carpet. Has anyone managed to break a cat or the habit of peeing outside the litter tray?
