Kidney Disease in Javaneses
Chronic kidney disease (CKD) is one of the most common conditions affecting Javaneses, and the leading cause of death in senior cats. The kidneys gradually lose their ability to filter waste products from the blood. In Javaneses, CKD often develops silently over years before symptoms appear. Early detection through regular blood work is the key to extending comfortable lifespan — SDMA testing can detect kidney disease when 75% of function still remains.
Prevalence
Very common — affects over 30% of cats over age 10
Typical Onset
7-15 years (often detected 10+)
Severity
Severe
Symptoms to Watch For
If your Javanese shows any of these signs, monitor closely and consult your veterinarian.
Risk Factors
- •advancing age
- •indoor cat lifestyle with inadequate hydration
- •previous kidney injury or infection
- •chronic dental disease
- •dry-food-only diet reducing water intake
Diagnosis
Blood work reveals elevated BUN, creatinine, and SDMA (SDMA is the earliest marker, detecting kidney disease when only 25% of function is lost vs. 75% for creatinine). Urinalysis shows dilute urine (low specific gravity) and proteinuria. UPC ratio quantifies protein loss. Abdominal ultrasound evaluates kidney size, shape, and architecture. Blood pressure measurement — hypertension is common. IRIS staging (I-IV) guides treatment.
Treatment
No cure — management focuses on slowing progression and maintaining quality of life. Renal diet (reduced phosphorus and moderate protein). Phosphate binders if phosphorus remains elevated. Subcutaneous fluids at home for dehydration. Anti-nausea medications (maropitant). Blood pressure medication (amlodipine, telmisartan). Erythropoietin for severe anemia. Potassium supplementation if needed.
Prevention
Annual blood work including SDMA for early detection (starting at age 7 for dogs, age 10 for cats — or earlier for predisposed breeds). Maintain hydration — provide fresh water and wet food. Avoid nephrotoxic medications (NSAIDs, certain antibiotics) without monitoring. Dental health reduces chronic bacterial kidney exposure. Prompt treatment of urinary infections.
When to See a Vet
See your vet if your pet drinks notably more water than usual or urinates more frequently. Annual blood work after age 7 catches kidney disease early. EMERGENCY: not urinating at all, severe vomiting, ammonia-smelling breath, or seizures.
