Yes, they are pretty sure they will open him up tomorrow. Earlier he told me the barium was moving pretty slow so he suspected an obstruction which is what I thought all along. I hate to put him through surgery, but something is obviously wrong. A friend suggested I take something that smells like us so he can get through the night. The vet is a real sweetheart and plans to go in a few times tonight to check on him tonight. He will do the surgery tomorrow and will let me pick him up Saturday night or Sunday. I wish Drs were as sweet as he is.
