Halo's vet appointment went very well. The ultrasound shows that the tumor is just a ball of fat growing on top of the liver and not inside. It also appears to have shrunk some since last month. The best news of all is the bloodwork.

ALT ~ An enzyme normally present in liver and heart cells that is released into the bloodstream when the liver or heart is damaged. The blood ALT levels are elevated with liver damage (for example, from viral hepatitis) or with an insult to the heart (for example, from a heart attack). Some medications can also raise ALT levels. ALT is also called serum glutamic pyruvic transaminase (SGPT).
Normal range is 10-100. Halo's in August: 131 In September: 35

AST ~ Also an enzyme found in the liver, red blood cells (RBCs) and in muscle tissue; damage to any of these can result in increased levels of AST in the blood. An elevation in AST signifies more severe damage to the cells than an elevation in ALT. AST was previously called serum glutamic oxaloacetic transaminase (SGOT).
Normal range is 10-100. Halo's in August: 272 In September: 17

CPK ~ Is an enzyme which is very useful for diagnosing diseases of the heart and skeletal muscle. This enzyme is the first to be elevated after a heart attack (3 to 4 hours). If CPK is high in the absence of heart muscle injury, this is a strong indication of skeletal muscle disease.
Normal range is 56-529. Halo's in August: 29,748 !! In September: 110



She also weighed in at a healthy 11 pounds. We go back in 3 months for retesting. Thank you all for your thoughts and prayers. Looks like we've dodged another bullet.
