Hector is a very special cat. He has a liver shunt. About 1 cat in 10,000 has a liver shunt. It is a congenital abnormality in the blood vessels that take the blood to the liver to be cleaned. In the case of a shunt, the vessels bypass the liver. He has to take medicine everyday and eat a special diet. He does get to enjoy Temptations as a very special treat. Chicken flavour only, please!
