Chronic kidney disease in cats
Chronic kidney disease is one of the most common conditions in older cats. It can't be reversed, but early management greatly extends quality of life.
What it is
The kidneys gradually lose their ability to filter waste and concentrate urine. It progresses slowly over months to years, so early detection through routine bloodwork matters.
Symptoms
- ●Increased thirst and urination
- ●Gradual weight loss
- ●Reduced appetite, nausea
- ●Lethargy, poor coat
- ●Bad breath (ammonia smell) in advanced cases
🔴 When to act now
- ●Not eating at all, repeated vomiting, or collapse
- ●Sudden worsening — see a vet promptly
Treatment & management
Management focuses on a kidney-support (low-phosphorus) diet, hydration, and medications to control blood pressure, phosphorus, and nausea. Regular monitoring slows progression. Many cats live comfortably for years after diagnosis.
