Fatty liver in cats is a disease caused by excessive fat deposition in the liver, which is commonly found in cats with obesity, poor diet and diabetes. If left untreated, it can lead to liver damage, increased inflammation, and eventually liver failure. The life expectancy of cats with fatty liver can vary depending on the individual cat, treatment measures and the severity of the situation. In general, the life expectancy of cats with fatty liver is very difficult to determine, mainly depending on the severity of the disease, and some serious life-affecting cases can make cats reduce their life expectancy, but as long as the amount of money is not too much, and cats are properly nourished, maintain moderate exercise, take the right medication and continue to go to the checkups, it is possible to increase the life expectancy of cats with fatty liver. To avoid the occurrence of cats with fatty liver, owners can allow their cats to adhere to physical exercise, reduce the consumption of human food by cats to avoid over-obesity, and ensure that the cat's diet is balanced, rich in proteins, low in fat and low in carbohydrates, to ensure that the nutrients needed in the cat's body are replenished. In addition, the cat's daily life environment should be kept clean and comfortable, and timely preventive treatment for pets, such as regular deworming, immunization and physical examination.
