Poorly concentrated urine is associated with an increased risk of developing chronic kidney disease in apparently healthy cats.
Clinical evidence update from Journal of the American Veterinary Medical Association
Clinical Context
Peer-reviewed veterinary literature continues to shape everyday decision-making for feline patients, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.
What the Study Evaluated
A study published in Journal of the American Veterinary Medical Association in 2026 evaluated poorly concentrated urine is associated with an increased risk of developing chronic kidney disease in apparently healthy cats..
Key Findings
To evaluate medical records from mature and senior cats stratified by urine specific gravity (USG; ≥ 1.035 or < 1.035) to examine the development of presumptive chronic kidney disease (CKD). 15,027 apparently healthy cats were evaluated for inclusion in a 2-year longitudinal retrospective study. Outcome during the study period was a presumptive CKD diagnosis or development of creatinine > 1.6 mg/dL and USG < 1.035 with consistent clinical signs. Cats were grouped by age (mature, 11 to 15 years; senior, > 15 years) and USG values for contingency and survival analyses. A CKD assignment was precluded in cases where historical information,...
Why It Matters for Veterinary Professionals
For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for feline patients.
Practical Interpretation
The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.
Clinical Takeaway
Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
