🐀 The Vet’s Guide to Rat Glomerulonephrosis in 2025 🩺

By Dr Duncan Houston BVSc – veterinarian & Ask A Vet founder. Glomerulonephrosis—also called chronic progressive nephropathy or glomerulonephritis in rats—is a degenerative kidney disease common in aging pet rats. Although irreversible, early recognition, tailored care strategies, and supportive services in 2025 can significantly improve your rattie's wellbeing and longevity.

🔍 Understanding Glomerulonephrosis

This chronic condition involves inflammation and damage to the glomeruli—the microscopic filtration units in the kidney—leading to protein loss, reduced kidney function, and eventual renal failure :contentReference[oaicite:3]{index=3}.

Histopathology shows glomerular sclerosis, tubulointerstitial fibrosis, dilated tubules, and proteinaceous casts :contentReference[oaicite:4]{index=4}.

👀 Clinical Signs to Watch For

• 🐾 Increased drinking (polydipsia) and urination (polyuria), often with overflow wetness :contentReference[oaicite:5]{index=5}.
• Weight loss, poor stamina, rough coat, lethargy.
• Swelling in face or limbs (rare), variable appetite.
• Labwork may show proteinuria and elevated kidney parameters.

🩺 Diagnosing the Disease

1. Physical exam—check hydration, palpate kidneys.
2. Urinalysis—dipstick for protein (≥300 mg/dL), pH, specific gravity for dilute urine :contentReference[oaicite:6]{index=6}.
3. Blood testing for urea, creatinine, electrolytes.
4. Imaging—ultrasound can detect structural changes and scarring.
5. Histopathology—used in research to confirm glomerular damage :contentReference[oaicite:7]{index=7}.

🏥 Supportive Management in 2025

While there's no cure, veterinary-supported protocols can slow progression and ease symptoms:

• 💧 **Hydration & Fluids:** Ensure free access to water; offer wet foods and administer sub‑Q fluids when needed :contentReference[oaicite:8]{index=8}.
• 🍽️ **Renal Diet:** Low protein/phosphorus mix, enriched with omega-3, vitamin B‑complex, and mild acidifiers :contentReference[oaicite:9]{index=9}.
• 🩹 **Medications & Supplements:** Phosphate binders, diuretics (e.g., furosemide), and vitamin E or low-dose retinoids can support kidney health :contentReference[oaicite:10]{index=10}.
• 🩻 **Anti‑hypertensives/Anti‑inflammatories:** In advanced cases, vets may use ACE inhibitors or steroids cautiously :contentReference[oaicite:11]{index=11}.
• ⚠️ **Infection Monitoring:** Treat urinary or secondary infections promptly.
• 🩼 **Gentle Exercise & Enrichment:** Light activity maintains muscle and supports appetite.

🏠 Home Care & Monitoring

• Accurate tracking of daily water intake, urine output, body weight, and coat quality.
• Encourage fluid consumption; use dropper-fed fruits or warm fluids.
• Clean urine soaked areas quickly to prevent skin irritation and odor.
• Provide a consistent, low-stress environment with soft bedding.

🌟 Prevention & Wellness

• Regular veterinary check-ups from middle age onward.
• Maintain diet balance—avoid high-phosphorus treats.
• Manage stress—offer environmental enrichment and stable routines.
• Watch for early warning signs: increased thirst/urination, coat changes.
• Offer omega‑3 fatty acid supplements and antioxidants such as vitamin E.

📚 Case Examples

Case 1: Elderly Polydipsia

"Mabel," 2.5 yrs old, presented with excessive drinking and dilute urine. Support plan included sub‑Q fluids, renal diet, and vitamin E. For six months, she maintained weight and energy.

Case 2: Proteinuria on Screening

A health check showed proteinuria. Early implementation of renal diet, low-dose retinoid therapy, and hydration support followed. Decline slowed, and coat regained condition.

⚠️ When to Consult the Vet Immediately

• Rapid weight loss, refusal to drink or eat.
• Signs of dehydration, incontinence, weakness.
• Blood in urine or odor, suggesting infection.
• Neurological signs: tremors or collapse.

✅ Summary Key Points

• Glomerulonephrosis is a chronic kidney disease common in aging rats; early detection improves outcomes.
