Yes.. I read all of that before I posted.
The reason why I don't think it's a urinary problem, is she started doing it right after my Sister-In-Law got here.
I have had my cat since she was a kitten, for a year now.
She has never peed anywhere but her box, now she is peeing in the living room carpet!! The only thing I can think of, is my Sister-In-Law has come to stay with us, and she started this right after she got here. HELP!! How do I make her...
