Yesterday I gave a cuttlebone to my tortoise. She ate it all just fine, but on one small section the hard part was there (idk how I missed it). Now, it was a small section for my size, but the chunk with the hard part was triangular and as large as the tortoise's mouth and it took a bit of swallowing. She seems to have swallowed it just fine but hasn't pooped since yesterday. Does the hard part get dissolved in the stomach or should I be worried?
