Head Tilt (Wry Neck / Vestibular Disease) in Rabbits
A neurological condition where the rabbit holds its head twisted to one side, often with loss of balance. Most commonly caused by E. cuniculi infection or inner ear infection. Treatable if caught early.

When to Act
🚨 Immediate Emergency Care
Symptoms & Signs
Head tilted to one side
Head consistently held at an angle, from slight tilt to 90+ degrees — sometimes the head is upside down.
Loss of balance / circling
Rabbit falls over, rolls, or walks in circles. May be unable to stand.
Nystagmus (eye flicking)
Eyes flick rapidly, either horizontally, vertically, or rotating.
Rolling
Uncontrollable rolling/flipping of the entire body in severe cases.
Inability to stand
Rabbit cannot maintain an upright position and lies on its side.
Behavioral Changes to Watch For
Pets can't tell us what's wrong. These behavioral changes are often the first clues that something is wrong.
🐾 Disorientation and distress
The world is literally spinning — the rabbit is terrified and confused.
What You May Notice:
Your rabbit cannot navigate their enclosure, knocks over bowls, and seems panicked.
Causes & Risk Factors
Causes
- •Encephalitozoon cuniculi (E. cuniculi) — protozoan parasite; the most common cause
- •Inner/middle ear infection (often Pasteurella spreading from the respiratory tract)
- •Trauma or head injury
- •Toxoplasmosis
- •Brain tumor (rare)
Risk Factors
- ⚠Exposure to E. cuniculi (transmitted via infected urine — very common in rabbits)
- ⚠History of snuffles or respiratory infection
- ⚠Stress-induced reactivation of latent E. cuniculi infection
How It's Diagnosed
- 1Neurological examination
- 2E. cuniculi antibody titers (IgG and IgM) — serial titers 2-4 weeks apart
- 3Otoscopic examination for ear infection
- 4Skull radiographs or CT if ear disease suspected
- 5Blood work to rule out systemic illness
Treatment Options
Fenbendazole (Panacur) for E. cuniculi
Antiparasitic treatment — the standard of care for suspected E. cuniculi.
Steps
- 1.Fenbendazole 20 mg/kg PO once daily for 28 days
- 2.Start treatment immediately — do not wait for lab confirmation
- 3.Combined with anti-inflammatory (meloxicam ± prednisolone)
- 4.Also treat all in-contact rabbits
Expected Outcome
Halts progression of neurological damage. Existing damage may be permanent.
Precautions
- !Treatment is most effective when started EARLY — within 24-48 hours of first signs
Anti-Vertigo Medication
Reduces the sensation of spinning and associated nausea.
Steps
- 1.Meclizine (Dramamine) — reduces vertigo symptoms
- 2.Diazepam in severe cases
Expected Outcome
Reduced disorientation and distress, allowing the rabbit to eat.
Precautions
- !Supportive care (padded enclosure, assisted feeding) is essential
Supportive Home Care for Head Tilt Rabbits
Essential for preventing complications while the rabbit recovers.
Steps
- 1.Padded enclosure — rolled towels as bumpers to prevent injury during rolling
- 2.Shallow food and water bowls — rabbit may not be able to reach normal height
- 3.Syringe feeding if rabbit cannot eat independently
- 4.Keep the rabbit in a small, safe space to reduce stress
- 5.Monitor for urine scald and keep the rabbit clean
Expected Outcome
Prevents secondary injuries and maintains nutrition during recovery.
Precautions
- !Be patient — recovery can take weeks to months
- !Some head tilt may be permanent
Common Medications Used
| Medication | Usage | Important Notes |
|---|---|---|
| Fenbendazole (Panacur) | Antiparasitic for E. cuniculi treatment | 28-day course. Start immediately when head tilt is observed. |
| Meclizine | Anti-vertigo medication to reduce dizziness | OTC motion sickness medication. Improves comfort and willingness to eat. |
Prevention
- ✓Routine fenbendazole prophylaxis in multi-rabbit households (controversial — discuss with vet)
- ✓Good hygiene — clean litter boxes frequently to prevent E. cuniculi transmission
- ✓Prompt treatment of respiratory infections
- ✓Quarantine new rabbits
When to See a Veterinarian
- 🚨ANY head tilt — this is an emergency, treat TODAY
- 🚨Loss of balance, circling, falling over
- 🚨Eye flicking (nystagmus)
- 🚨Rabbit rolling uncontrollably
Frequently Asked Questions
Can a rabbit with permanent head tilt live a good life?
Prognosis
Variable. With early aggressive treatment, 60-70% of rabbits recover to have a good quality of life. Some retain permanent mild head tilt. Severe cases with rolling may require extensive nursing care. The head tilt itself may be permanent even after successful treatment — many rabbits adapt well to life with a tilt.

Rabbits' teeth grow continuously throughout their lives. When teeth don't align properly (malocclusion), they overgrow, causing severe pain, inability to eat, and secondary infections.
