I got some cuttlebones...just wanted to know how to remove the upper hard layer easily.. n my torts nvr try to eat em when thet are whole..But when i smash it into small peices they eat it.
If I was to start worrying about feeding whole cuttlebone now, I would also have to start worrying about giving them snails with those hard, crunchy shells too! But I don't.
Sometimes I grater the cuttlebone and mix it with their greens, but I feed it whole too.
I just use my fingernails to break small pieces off the hard backing. One of my water turtles cut his mouth on it one time so I always remove the backing now
