Is it fresh (red) blood, or dark/black blood? Or is it pinkish?
Pink can be parasites, so I’ve heard. Red would indicate that maybe it was a large movement and some superficial tearing occurred. Dark would indicate internal bleeding and far more serious.
In any case, your safest bet is to send a fecal to a vet.
Good luck!
It was definitely red. Hoping to get an appointment for Saturday morning. The urate did look a bit large but it’s definitely worth getting her checked out.
