Chronic Kidney Disease in Cats

Chronic Kidney Disease in cats is one of the most prevalent diseases in older cats, affecting up to 40% of cats over the age of 10 and 80% of cats over the age of 15.

Like in humans, healthy kidneys perform many functions in cats, including filtering the blood, making urine, and helping to regulate blood pressure.

Chronic Kidney Disease in cats refers to the persistent loss of kidney function over time and can have many health consequences.

The only known risk factor for the development of CKD in cats is age, so it is very important for all senior cats to be regularly monitored for this disease.

In the early stages of Chronic Kidney Disease in cats, it is very common for cats to show no obvious clinical signs, as their body is able to compensate for the decrease in kidney function. As the kidneys lose their ability to concentrate urine effectively, cats may begin to urinate greater volumes and drink more water to compensate. The loss of important proteins and vitamins in their urine may contribute to abnormal metabolism and loss of appetite. Eventually, cats with Chronic Kidney Disease may experience a buildup of the waste products and other compounds in the bloodstream that are normally removed or regulated by the kidneys. This accumulation may make them feel ill and appear lethargic, unkempt, and lose weight.

Dietary modification is an important and proven aspect of treatment for Chronic Kidney Disease in cats. Therapeutic diets that are restricted in protein, phosphorus and sodium content and high in water-soluble vitamins, fiber, and antioxidant concentrations may prolong life and improve quality of life in cats with Chronic Kidney Disease.
