— Written by Dr Duncan Houston BVSc, founder of Ask A Vet —

Introduction

Lead poisoning is a serious but preventable condition in guinea pigs. 🏠 These curious pets may chew on lead-painted surfaces, contaminated soil, or old toys, leading to toxins accumulating in their body. In this updated 2025 guide, we cover signs, diagnosis, treatment including chelation, home care, and strict prevention to protect your cavy.

🔍 1. Sources of Lead Exposure

• Gnawing on lead-based paint, old window frames, linoleum, or plumbing materials :contentReference[oaicite:2]{index=2}
• Ingesting lead-contaminated dust, soil, fishing weights, or old batteries :contentReference[oaicite:3]{index=3}
• Chewing on household items or toys coated in lead :contentReference[oaicite:4]{index=4}

⚠️ 2. Recognizing Symptoms

Lead disrupts the nervous system, GI tract, blood cells, and hearing. Watch for:

• Gastro symptoms: constipation, diarrhea, abdominal pain :contentReference[oaicite:5]{index=5}
• Neurologic signs: wobbling, incoordination, tremors, seizures :contentReference[oaicite:6]{index=6}
• Behavioral changes: hiding, anxiety, aggression :contentReference[oaicite:7]{index=7}
• Weak appetite, lethargy, weight loss :contentReference[oaicite:8]{index=8}
• Hearing issues: lead-induced neurotoxicity can impair auditory pathways :contentReference[oaicite:9]{index=9}

🔬 3. Diagnosing Lead Poisoning

• Blood lead level: Confirm exposure via lab test :contentReference[oaicite:10]{index=10}
• CBC & biochemistry: May reveal anemia, kidney strain, inflammation :contentReference[oaicite:11]{index=11}
• Radiographs: Detect lead fragments in GI tract :contentReference[oaicite:12]{index=12}

🩺 4. Treatment Options

• Chelation therapy: Age-appropriate chelators (e.g., edetate calcium disodium, succimer). Often used in pets :contentReference[oaicite:13]{index=13}
• Cathartics: To speed elimination of lead particles :contentReference[oaicite:14]{index=14}
• Supportive care: IV or SQ fluids, nutritional support, anti-seizure meds when needed :contentReference[oaicite:15]{index=15}
• Thiamine supplement: May ease neurological issues :contentReference[oaicite:16]{index=16}

⏳ 5. Prognosis

Depends on exposure level and organ damage:

• Reversible: Mild exposure—GI and blood effects usually recover.
• Irriversible: Neurological damage and hearing loss often long-term :contentReference[oaicite:17]{index=17}

🏠 6. Home Recovery Care

• Safe housing: Remove all lead hazards—no painted wood, linoleum, or batteries.
• Clean environment: Regular cage cleaning to reduce lead dust.
• Nutrition: High-fiber hay and fortified pellets; encourage eating.
• Monitor: Track appetite, stool, weight, behavior post-treatment.

🛡️ 7. Prevention & Safe Environment

• Inspect and remove old painted items, lead-laden finishes, or contaminated toys.
• Avoid areas with peeling paint, old plumbing, or fishing gear in cavy spaces.
• Wash hands and surfaces after outdoor soil contact.
• Provide chewing wood that’s lead-free to redirect gnawing behavior.
