Pica:  The Desire To Eat Things That Are Not Food.

I woke up to the sound of Kumani purring next to me but also a weird
sound....bunt, *snap*, chew chew chew, *purrrrr.*

Kumani was plucking lint balls off my blanket, chewing them, and EATING
THEM.

I don't know how long she was doing it before I woke up, but the fact
that these fuzzy lint balls are probably half synthetic means I don't
want her eating any more of them.  I saw her eat at least 5 before I
realized what she was doing, got up, and put the blanket away in the
closet.
