Kidney failure in cats is divided into chronic renal failure and acute renal failure. The causes of chronic renal failure may be infection in other parts of the body, problems with the immune system, hereditary poor kidney function, and decline in kidney function with age, etc. . Acute kidney failure may be caused by a disease that causes dehydration or fluid loss, a sudden worsening of chronic kidney failure, or the inability to urinate normally. Generally speaking, acute renal failure has a high chance of recovery, while cats with chronic renal failure generally have only one year to live.
