I have a question about Poop -

[nanyque]

So, Saffron hasn't been eating much lately, and been doing a ton of digging at stuff in her tank. She's about 6 months old. This was her poop this morning. The urate is normal, the 3 different bits of dark poo is not (it's usually one long bit), but the thing I'm most curious about is that bigger yellow thing. It was fairly large, hard, and when broken apart the interior was a powdery, white substance. The entire poop smelled worse than her usual, though it wasn't particularly slimy. rather wet, as you can see by the discoloration of the papertowel around it. Does anyone know what that is???
