It's harder to make out, but the two linear squiggles at 11 and 1 o'clock are blue crayon shavings edge-on. That makes it the Little Black Shit's crappola.
I'm surprised that there is so little hair in this sample. LBlS was the cat, you'll recall, who had major surgery last May, for The Mother of all Trichobezoars (hair ball). She has been receiving both Kristalose (for constipation) and Petromalt (to help hair pass through her gut), so perhaps that has been controlling the ingested hair situation for her.
I definitely have to get LGS on Petromalt.
