Thank you very much, it must have worked, the vet did not seem to find anything much really, said he had a bit of a squishy tummy,not sure what he means there, and maybe an infection could occurr, so put him on ten days antibiotics, he said he could have giardia, somehow I think it was pretty inconclusive really, he has a special purina intestinal food to eat for a few days as well, he scoffed it down no problem so he cannot be too bad.

My sister said he had a few mouthfuls of fresh snapper straight out of the sea on saturday, I wonder if it was just too fresh and upset his tummy, still don't know why there would be any blood present, I thought maybe he was constipated or had colitis, but appears not, so he should be well on the mend soon, heres hoping and thanks for your kind words and thoughts.
