Found animal scat on my patio. Looks like short gray rolled up paper, not pellets. Squirrel, Raccoon Opossum?

I dropped some black oil sunflower seeds on my patio when I filled my bird feeder. The feeder was left alone and northing else was disturbed which doesn't sound like a squirrel or racoon. I don't have any idea. Anyone ever seen anything sounding like that?Found animal scat on my patio. Looks like short gray rolled up paper, not pellets. Squirrel, Raccoon Opossum?
