Help! Need Pro advice?! Is this raccoon pee?!?

Hi guys. Need some pro advice. So story is, I had some critters get into my attic but the animal control guy said something was in there (years old droppings
and disturbed insulation) but animal I heard the other day has since left as he didn't see anything that would indicate camping critters like fresh poop or anything like that. There's also a stain on ceiling in one upstairs room which might be coon pee! Roof is sealed and they came in thru small hole under outside chimney box.
Take a look at these pics. Does this look like coon pee? The room smells like cat pee!!! Wth? Thx
