Fatty liver disease, also known as Hepatic Lipidosis, occurs when large amounts of fat are deposited into the cat’s liver. The main function of a Russian Blue or other cat’s liver is to produce chemicals necessary for digestion and the detoxification of the body. An infected cat will most likely stop eating and become undernourished. When this happens his body naturally takes fat from reserves and transfers them to the liver in order to process it into energy. A cat’s liver is unable to process the fat. Symptoms of fatty liver disease include prolonged anorexia, rapid weight loss, vomiting, diarrhea, constipation, muscle wasting, depression, downward flexion of the head and neck, yellowing of the eyes, drooling, and possible collapse in later stages. If your cat has any of these symptoms, contact your most reputable veterinarians Rochester NY immediately. Diagnosis and treatment are needed right away in order to prevent further damage to the liver.
