Called Bugout for a bug inpection, and the guy said i have mice in my attic. Told me this is a mouse pee stain. Is that right?

Fun fact, cats aren't actually very effective at killing all the rodents. They've done studies and basically the cats just make them really skiddish and they hide so you never see them. They kill one here or there but the real benefit is getting them out of sight.
