I believe that pyramiding occurs when a tortoise does not get to live a normal life. I believe it's caused by many things such as, lack of humidity (living inside), dehydration, poor diet, MBD, stress, nothing to rub the shell smooth, overfeeding, underfeeding, ect.... We cannot properly mimic their natural habitat, so it's hard to prevent pyramiding. I think we're focusing on just diet way too much. It's a lot of things combined, sometimes it's hard to look at the bigger picture.
