Hepatic Lipidosis or fatty liver disease is a one of the most common and most severe liver disease in cats including the Russian Blue. The main function of a cat’s liver is to produce chemicals necessary for digestion and the detoxification of the body. Fatty liver disease occurs when large amounts of fat are deposited into the liver. For reasons often unknown, a cat will start to lose weight and become undernourished even though his diet hasn’t changed. As a result, his body will transfer fat reserves to the liver to be converted into the proteins needed for energy. A cat’s liver is unable to handle this large amount of fat and may become swollen. In addition, the liver is no longer able to process other materials including red blood cells. As a result you may see a yellowing of the cat’s eyes.
