Rabbit Head Tilt UK — Causes, Treatment & When to See a Vet

According to the RWAF, head tilt (torticollis) means a rabbit holds its head at an angle — often sharply to one side. Balance is controlled by the inner ear and brain, so tilt usually signals neurological or ear disease.

Affected rabbits may:

• Lean or roll to one side
• Fall over when trying to hop
• Circle repeatedly
• Have rapid eye flickering (nystagmus)
• Struggle to eat or drink
• Develop gut stasis from pain and immobility

Head tilt is distressing for rabbits and owners, but many rabbits recover or adapt with proper treatment and nursing.

E. cuniculi (Encephalitozoon cuniculi)

According to the RWAF and PDSA, E. cuniculi is a microscopic parasite affecting up to half of UK rabbits — often without symptoms until stress or illness triggers brain inflammation. Head tilt is a classic sign.

See our dedicated guide: Rabbit E. cuniculi UK.

Inner ear infection (otitis interna)

Bacterial infection spreads from the outer ear or dental disease into the inner ear, disrupting balance. May accompany:

• Head shaking or ear scratching
• Discharge from one ear
• Facial nerve weakness (drooping lip or eye on one side)

Dental disease

Overgrown tooth roots can press on nerves and ear structures — see Rabbit overgrown teeth UK.

Other causes

• Trauma — falls or predator attacks
• Stroke-like vascular events — more common in older rabbits
• Toxins — less common but must be ruled out
• Brain abscess or tumour — especially if gradual onset in older rabbits

Your vet will distinguish causes through examination, history, and sometimes imaging or blood tests.

Treatment depends on the underlying cause:

E. cuniculi:

• Anti-parasitic medication (fenbendazole) — course length per vet protocol
• Anti-inflammatory drugs
• Supportive nursing over weeks

Ear infection:

• Culture-guided antibiotics
• Long courses — inner ear infections need weeks of treatment
• Pain relief essential

All cases:

• Syringe feeding critical care formula if not eating
• Subcutaneous fluids if dehydrated
• Pain relief — rabbits in pain stop eating
• Safe padded enclosure — prevent injury from rolling
• Eye lubrication if the rabbit cannot blink normally on affected side

Hospitalisation helps stabilise nutrition and hydration in the first days.

According to the RWAF, long-term nursing makes a real difference:

• Padded pen — no hard floors; prevent rolling into walls
• Hand-feed hay and critical care until the rabbit eats independently
• Keep litter tray and food within reach on the accessible side
• Groom if the rabbit cannot keep itself clean
• Monitor droppings daily — quantity matters as much as eating
• Patience — improvement may take weeks; some retain a mild permanent tilt

Many rabbits with a residual tilt live happy, bonded lives with minor adjustments.

• Regular vet checks including teeth and ears
• Treat E. cuniculi when diagnosed — discuss testing with your vet
• Prevent ear infections — avoid water in ears; treat outer ear issues promptly
• Hay-first diet and dental monitoring
• Reduce stress — stress triggers E. cuniculi flare-ups
• Secure housing — prevent falls and predator trauma
