@Amber Lynne: Nope. That jerk always has to go on carpet. (Or the bed!) so we can never leave him alone in a bedroom. Even now we have to always leave all of the bedroom doors closed at all times. Here I thought that we would be good cause everything else is hardwood, but instead he has decided to pee on our area rugs and the bathmats. UGHGUGGHGH
@eyry: OMG That is probably totally what happened. When I got him he was already fixed, but if it happened late with the first owner that would make a lot of sense. The marking has cost me a lot of money over the years.
Also when I left my old condo, I got the carpet cleaned in my bedroom, I didn't even live there for two years and not even the carpet cleaner could believe how much there was in the carpet. I was so embarrassed. Like if even the carpet cleaner has that reaction, you know it's a lot.
