So my pancake was soaking like he does everyday and everything was normal until he passed what appeared to be a white stone the size of a small pea. At first I thought he swallowed a rock but then I realized that he is currently using the Zoomed Reptile Carpet so there are no rocks to chew on. I looked at the stone and noticed that I could crush it with force into fine grains. That's when I knew it was either very hard urates or calcium. I usually sprinkle very small amounts of reptile calcium + D3 on the food every Monday and sprinkle reptile vitamins on food the first of every month. He also goes outside for 1 hour everyday. Can someone give me their opinion on what was passed and how to prevent it from happening again. Any advice would be appreciated.
