That’s why I said usually.I’ve seen deer poop like that, it’s not always pebbles
i have also never seen bear scat that looked anything like that... spring time, their scat is more pellets, but big teardrop shaped pellets, and you can still see the grass fibers all through it... then it gets more soft piles with a hint of loafy-ness, then you go into berry season where it's berry log fruitcakes, then you get a mixed bag of chunky apple sauce, cream of mushroom soup, and acorn patties.No scat expert but I've seen deer poop like this very often. All the bear scat I personally seen in person never looked like that.
