We always tell folks to keep a cuttlebone in with their tortoises. Some gnaw on them right away, while others don't touch them for months. I caught this female Redfoot in the act of eating a piece of cuttlebone.
Here she is coming up and checking out a hunk.
Then instead of gnawing on it, she takes the entire hunk and chews on it.
