Lunchbox’s first Turtle Bone:
Turtle Bone is, in fact, bone. It’s cuttlebone. That’s right, the skeleton of a cuttlefish. It looks and feels like a big hunk of chalk, complete with powdery dust that comes off when you touch it:
The whole piece is about 12 cm (just short of 5 in) long–clearly too big for Lunchbox (although that wouldn’t stop him from trying to eat the whole thing), so I broke off a small piece for him (it’s quite easy to break apart).
Turtle Bone is used as a natural source of calcium, and its rough edible surface prevents overgrown mandibles (beaks). It can also help to curb unwanted chewing behavior, but that’s not really an issue with Lunchbox.
