Morty has been eating dandelions. Pink pee and urate is a common side effect. The "white" (pink ) stuff is urate and is how your tort excretes excess proteins. It isn't poop. Don't worry about the pink!
I misspoke: urate, not poop. But I haven't given her any dandelions, and the urates have always been white before. You don't feel that it could be blood related to infection?
