@PriestessAvenara It was only once. I was shocked too, when I saw it. There was a screenshot, but it is now somewhere on the external disk.
After that I reset the lot. By the way it was on the biggest lot in Willow Creek (Don't remember the name, unfortunately) Near the door mat.
So "Can you put flooring down on it? Can you clean the pee puddles or does it tell you only a neat freak would try to clean the ground?" Yes, with flooring all is ok. And yes, the puddles are cleanable.
I think it was some weird bug. Don't know what could reason it, though.
I think after this I started to forced the dogs to go for a walk (with mods, unfortunately).
