Rabbits are masters at hiding illness—a survival instinct from their wild ancestors. This makes it crucial for rabbit owners to understand their bunny’s normal behavior and recognize subtle signs of health problems. This comprehensive guide covers common rabbit health issues, prevention strategies, and when to seek veterinary care.
Understanding Rabbit Health Basics
Why Rabbits Hide Illness
In the wild, rabbits are prey animals. Showing weakness makes them targets for predators. This instinct remains strong in domestic rabbits, meaning:
- Symptoms often appear late in illness
- Subtle changes can indicate serious problems
- Regular observation is essential
- Preventive care is crucial
Normal Rabbit Vital Signs
| Sign | Normal Range |
|---|---|
| Temperature | 101-103°F (38.3-39.4°C) |
| Heart rate | 130-325 beats per minute |
| Respiration | 30-60 breaths per minute |
| Eating | Continuous (many small meals) |
| Drinking | 50-150ml/kg per day |
| Pooping | 200-300 poops per day |
Daily Health Checks
Perform these checks every day:
- Eating and drinking - Is appetite normal?
- Poop production - Size, shape, quantity normal?
- Activity level - Usual energy and curiosity?
- Behavior - Any unusual hiding or aggression?
- Eyes - Clear, bright, no discharge?
- Nose - Clean, no discharge?
- Ears - Clean inside, no odor?
- Teeth - No overgrowth or drooling?
- Body condition - Neither too thin nor overweight?
- Mobility - Moving normally, no limping?
GI Stasis: The #1 Emergency
What Is GI Stasis?
Gastrointestinal stasis is a potentially fatal condition where the digestive system slows or stops. It’s the most common rabbit emergency and requires immediate veterinary attention [Journal of Exotic Mammal Medicine].
Causes

- ⚠️ Weight loss
- ⚠️ Drooling
- ⚠️ Watery eyes (tooth roots press on tear ducts) Treatment:
- Regular trimming by veterinarian
- Extraction in severe cases
- Dietary modification
Molar Spurs (Sharp Points)
Molars develop sharp edges that cut tongue and cheeks. Symptoms:
- ⚠️ Selective eating (avoiding hard foods)
- ⚠️ Dropping food
- ⚠️ Excessive salivation
- ⚠️ Bad breath
- ⚠️ Weight loss
- ⚠️ Reduced grooming Treatment:
- Veterinary burring under anesthesia
- Regular checkups (every 6-12 months)
Prevention

Respiratory Infections (Snuffles)
What Is “Snuffles”?
Upper respiratory infection, often caused by Pasteurella multocida bacteria. Highly contagious among rabbits.
Symptoms
- ⚠️ Nasal discharge (white or yellow)
- ⚠️ Sneezing
- ⚠️ Watery eyes or discharge
- ⚠️ Matting of fur on front paws (from wiping nose)
- ⚠️ Labored breathing (severe cases)
- ⚠️ Head tilt (if infection spreads to inner ear)
Causes
- Bacteria (Pasteurella, Bordetella, etc.)
- Stress - Weakens immune system
- Poor ventilation
- Ammonia buildup from dirty litter
- Dental disease (tooth roots affect sinuses)
Treatment
- Antibiotics - Long course (4-6 weeks minimum)
- Nebulization - In severe cases
- Supportive care - Fluids, nutrition
- Environmental changes - Better ventilation, cleaner habitat
Note: Snuffles often becomes chronic. Antibiotics control symptoms but may not cure completely.
Prevention
- ✅ Good ventilation
- ✅ Clean litter regularly (daily spot clean, weekly full clean)
- ✅ Minimize stress
- ✅ Quarantine new rabbits
- ✅ Regular vet checkups
Ear Infections
Types
Outer Ear (Otitis Externa)
Causes: Mites, bacteria, foreign objects Symptoms:

FAQ
Q: How can I tell if my rabbit is in pain?
A: Signs include: teeth grinding, hunched posture, reluctance to move, decreased appetite, aggression, hiding, and rapid breathing. Rabbits are very good at hiding pain, so any behavior change warrants attention.
Q: Why is my rabbit’s urine red/orange?
A: Rabbit urine color varies widely (yellow to red to orange) and is often normal. However, bright red urine or blood-tinged urine indicates a problem. If concerned, collect a sample for your vet.
Q: How often should my rabbit poop?
A: Rabbits produce 200-300 poops per day. A healthy rabbit should be pooping regularly throughout the day. Significant reduction or cessation is an emergency.
Q: Can I give my rabbit human medications?
A: Never give human medications without veterinary guidance. Many are toxic to rabbits. Always consult your vet first.
Q: Do rabbits need vaccinations?
A: Depends on your location. In the UK and Europe, rabbits need myxomatosis and RHD vaccinations. In the US, no routine vaccinations are required (but ask your vet about RHDV2).
Q: How long do rabbits live?
A: With proper care: 8-12 years (some live 14+ years). Indoor rabbits typically live longer than outdoor rabbits.
Q: Should I spay/neuter my rabbit?
A: Yes, highly recommended. Spaying prevents uterine cancer (80% risk in unspayed females), and neutering reduces aggression and marking. Both improve behavior and lifespan.
