So I was giving Sheldon my cherryhead tortoise a bath today and he peed and then this came out... What is it??

Are you talking about the dark spots next to the light reflection?

Yes the yellow spots.

I was afraid you'd say that...I don't have a clue what they are. Colored urates? I'm sorry, I can't help...
