Cat Kidney Disease: Early Signs and Prevention

Why CKD Is So Common

Chronic kidney disease affects 30-50% of cats over age 10. Symptoms often don't appear until 75% of kidney function is lost.

Early Warning Signs

• Increased thirst and urination
• Gradual weight loss despite normal appetite
• Occasional vomiting
• Decreased grooming
• Bad breath with ammonia smell

Diagnostic Tests

• SDMA: Detects dysfunction at 25% function loss
• Creatinine: Elevated after 75% function loss
• BUN: Affected by diet and hydration
• Urine specific gravity: Concentration ability

Prevention

• Adequate hydration: wet food, water fountains
• Healthy weight maintenance
• Avoid nephrotoxic medications
• Regular dental care

Managing Early-Stage CKD

Prescription renal diet, phosphate binders, and subcutaneous fluids can maintain quality of life for years.
