In brief
Increased thirst, larger urine clumps, weight loss, nausea and reduced appetite can be early signs of chronic kidney disease. Blood tests alone do not provide the whole picture.
What chronic kidney disease means
The kidneys regulate water balance, remove waste, support blood pressure and contribute to red blood cell production. Chronic kidney disease is usually progressive, but its speed and impact vary considerably between cats.
Early signs
- Gradual weight or muscle loss.
- Drinking more and producing larger urine clumps.
- Variable appetite, nausea or vomiting.
- Constipation, dehydration or a dull coat.
- High blood pressure may cause sudden blindness or neurological signs.
A complete assessment
Creatinine and SDMA are useful, but should be interpreted alongside urinalysis, urine protein, blood pressure, phosphorus, potassium, haematocrit and the cat’s hydration and muscle mass. Imaging and urine culture are indicated in selected cats.
Treatment priorities
Plans may include a kidney diet, maintaining hydration and calorie intake, controlling phosphorus and blood pressure, treating proteinuria, nausea, low potassium, anaemia or infection, and monitoring trends. Treatment should follow the cat’s stage and individual complications.
When to contact the veterinarian urgently
A cat that stops eating, repeatedly vomits, becomes profoundly weak, strains without producing urine or suddenly loses vision needs prompt assessment.
Conclusion
Regular senior screening can identify kidney disease before a crisis. Earlier intervention often means more options and better quality of life.
