Last week My leopard peed very dark urine during her soak. I watched her the next few days and I didn't see that again until today. She had the dark urine again and also pooped a small rock. My teen daughter was helping clean her after her soak and found the little rock. I think my tortoise may have eaten it in her outside enclosure some time when she was out last week. Could she have been bleeding trying to pass it? Is there anything I should be careful to look for or concerned about right now? Thanks in advance.
