Gabe's Liquid Diet

My guinea pig, Gabriel, is fighting an Upper Respiratory Infection this month. He was treated the first week in December with antibiotics and seemed to be getting over it. Then a few days after being off the Baytril he took a turn for the worse and refused to eat or even move around much. I guess he was taken off the medicine too soon. After a second visit to the vet on Christmas Eve he is back on his antibiotics. The doctor said he is right on the edge of being in critical condition. So over the next 48 hours it is extremely important that I keep him warm, hydrated, and try to get as much food in him as possible. Since he is refusing to eat on his own I've had to force feed him. I made a couple of liquid shakes to syringe to him.
