I need help! I have 13 year old male cat that has had this pattern of behavior his whole life. Any time he gets unhappy or stressed about something he finds a spot in the house and pees on the carpet. I have spent countless hours and countless dollars on Nature's Miracle over the years to clean up after him and I just don't know what to do to get him to stop. There is absolutely no chance that he has a UTI or any medical condition because the only time he pees on the carpet is when he's unhappy or stressed - all of the rest of the time he pees in the cat box right where he should. The worst is when I travel and have to leave him and my other two cats home alone for a week with visits from my parents to feed them, etc. Basically I have two questions. One, how do I get him to stop peeing on the carpet when he's unhappy or stressed? Two, how do I get the old and new urine spots cleaned up once and for all? I've always used Nature's Miracle, but I'm not convinced it's doing the best possible job. I've seen people in this forum suggest Urine-Off and Vodka as well as other products. What's the absolute best thing to use.
