Chronic Kidney Disease (CKD)

descriptionOverview

Chronic kidney disease is the gradual, irreversible loss of kidney function over months to years. It's the leading cause of death in older cats. The kidneys filter waste, regulate blood pressure, and produce hormones — when they fail, toxins accumulate in the blood. Early detection through blood and urine tests is crucial, because by the time symptoms appear, 75% of kidney function may already be lost.

restaurantHow Nutrition Helps

Nutrition is the cornerstone of CKD management. Phosphorus restriction is the single most important dietary change — high phosphorus accelerates kidney damage. Therapeutic kidney diets with controlled protein, low phosphorus, added omega-3 fatty acids, and increased B vitamins have been proven to extend survival by 2-3x compared to regular food. Starting a kidney diet early (IRIS Stage 2) gives the best outcomes.

Gentle, stress-free activity maintains muscle mass and quality of life. Cats with CKD benefit from low platforms and easily accessible water stations. Avoid strenuous exercise which increases waste products the kidneys must filter.
