My 4 year old female Bombay whom I have had since she was 8 weeks old has started urinating in my bedroom since our move to a new home a year ago. I've gotten her additional litter boxes placed throughout the house and there is no change. The behavior is not daily - maybe once every month or so - but no amount of extra attention or special treatment stops her. Even spraying her with water is ineffective. I've tried placing her in a carrier when she misbehaves, but she scratches so hard that she tears her little feet open. Is there anything else I can try?
