Cuttlebone How Do Torts Know

[katfinlou]

Ive never seen my tort eat cuttle fish but today Belle looks like she's just stuck her head into a tub of baby powder, her face is all white so she must chow down on it quite happily when im not looking. After all the eggs she's laid recently she's probably due a calcium top up bless her

They obviously know. My box turtle chewed on her cuttlebone obsessively as a fast growing baby. She is over 3 years old now and her growth has slowed down considerably. She has maintained the same SCL and weight for sometime now and I can't remember the last time she touched her cuttlebone. So obviously it's instinctual.
