His liver function numbers went from in the 700s to the 500s so that means no cancer. woot! They're going to wean him off the fluids today and I can get him tomorrow. They have him on a liver healing supplement and I am to continue that for 3 weeks. Then they are going to test his blood again. If his numbers aren't completely normal, they're going to do a liver biopsy, as it probably means that he has liver disease. Keep your paws crossed for Kahlua.
