Just putting back my pigs and found a piece of Carefresh in their cage that looked like it had been wet and then dried pinkish. I'm wondering if this could be blood in someone's urine... but when my hedgehog had bloody urine it dried brown. Just wondering if anyone has insight into odd urine colours... I may have to put in white Carefresh to see more clearly. No one shows signs of a UTI- no squeaking while peeing, etc. What would dried bloody urine look like on brown paper?
