Hi my Herman tortoise is 14 years old, I got him when he was 8weeks old. During the night he passed two egg shaped hard stone like things, they are quite big and I was so very shocked! Does anybody know if they are bladder or kidney stones and will he be ok?? Underneath him there is a reddish line and he looks swollen by his tail end, I've bathed him and he is eating normally. Any suggestions would be greatly appreciated.

Hello,
