Overview of chronic kidney disease
Chronic renal failure, also known as kidney disease, is a common problem in cats. One in three cats will develop chronic renal failure during her lifetime. Your cat’s kidneys are critical for normal bodily functions, such as the removal of toxic metabolic waste products from the blood, and regulation of bodily fluids and hormones. What does chronic kidney disease mean? "Chronic” means long-lasting; therefore, chronic renal failure simply means that there is a decline in the kidneys’ ability to function over a long period of time.  Because the kidneys impact other areas of the body, the changes that occur as a result of chronic kidney disease impact many other bodily systems, as well.

If you notice ANY of these symptoms in your cat, you should contact your veterinarian ASAP! They are indicators of many serious diseases and conditions.
