Cttage Cheese is good for them, I have heard that Caesars is not good but everyone has different opinions. Ummm... was the blood kinda of watery? Have you tried giving him something for his upset stomach? Usually you can tell it is a upset tummy because their rear ends will pwehh pwehhh smell pretty strong. Maybe 1/2 cc of pepto ???? You can put him on bolied chicken and white rice for a bit and see if you notice a change, something is better than nothing for now.... and don't forget some nutrical!
