Hello,
I recently moved into a short-term housing unit, and this morning I found black spots on the pillow underneath which I sleep. No clue if it was there beforehand or not (the linens were brought in by a housekeeping service after we arrived). There are no other stains on the mattress or pillow. Would you say that this is fecal matter?
