Companion Cat Chronic Kidney Disease Management

Chronic kidney disease is the leading cause of death in older cats, and proactive management significantly extends comfortable life expectancy when started early.

Key Facts

CKD affects approximately 30 percent of cats over age 12 and up to 80 percent of cats over age 15
Early CKD is detectable through SDMA blood test 17 months before creatinine elevation
Dietary phosphorus restriction is the most evidence-supported intervention for slowing CKD progression
Subcutaneous fluid administration at home extends comfortable life for cats in later CKD stages
Hypertension secondary to CKD causes organ damage requiring separate treatment
Quality of life assessment tools help guide management decisions as CKD progresses

Welfare Considerations

CKD welfare management is fundamentally about extending comfortable life rather than merely extending biological life. Cats with early CKD managed with appropriate diet and regular monitoring can maintain good quality of life for years. As disease progresses, management complexity increases: subcutaneous fluids address dehydration that causes nausea; anti-nausea medications improve appetite; phosphorus binders reduce uremic toxin accumulation. The welfare challenge is recognizing the transition point where treatment burden exceeds benefit, requiring regular quality of life assessment using validated tools.

What You Can Do

Begin annual SDMA testing for cats over age 8 to detect CKD early
Discuss CKD-specific dietary management with your veterinarian at diagnosis
Learn subcutaneous fluid administration technique if your cat progresses to later CKD stages
Establish quality of life assessment practice to guide management decisions as CKD progresses
