Cat Feline Interstitial Nephritis Welfare

Chronic interstitial nephritis is the most common form of feline kidney disease and requires early detection and long-term management.

Key Facts

Chronic interstitial nephritis causes progressive renal fibrosis and functional decline
Many cats show no signs until 75% of kidney function is lost
Annual blood testing detects CKD years before clinical illness develops
Renal diets significantly slow progression when started at early stages
Phosphorus restriction is a key management strategy for protecting remaining function

Welfare Considerations

Chronic kidney disease causes progressive accumulation of toxins that cause nausea, lethargy, and deteriorating quality of life. Early detection through routine annual testing allows dietary and medical intervention that significantly slows progression and maintains quality of life for longer. Without early detection, cats present in advanced disease where intervention is less effective.

What You Can Do

Request annual kidney blood testing for cats over 7 years
Start renal diet management at early-stage CKD rather than waiting for advanced disease
Monitor kidney function every 3-6 months in diagnosed CKD cats
