Rabbit bonding: how to pair two rabbits

Why rabbits need a partner

Rabbits are social animals, and the RSPCA says they should live with at least one other friendly rabbit unless a vet or behaviourist advises otherwise. A person, however devoted, cannot groom them, sleep pressed against them at 3am or keep watch while they eat. Wood Green lists the signs of a lonely rabbit: hiding, huddling in a corner, little interest in the world, and grunting, boxing or biting in its own space.

A guinea pig is not a substitute. Both the Rabbit Welfare Association and Wood Green advise against mixing the two, since rabbits can kick and injure guinea pigs and the two species speak a different body language.

Which rabbits bond best?

A neutered male and a neutered female is the easiest and safest pair. Other pairings can work, but they carry more risk of fights. Choose rabbits of a similar size and age where you can: Wood Green warns that a giant and a small breed together puts the smaller rabbit at more risk during mixing.

These ratings come from the House Rabbit Society. It adds that bringing a girl home to an existing boy tends to go better than the other way round. The easiest route of all is a rescue: many rescues let your rabbit meet a few possible partners and help with the introduction, which the Rabbit Welfare Association recommends if you have never bonded rabbits before.

Neutering before bonding

Both rabbits must be neutered before they live together. Unneutered rabbits fight and breed, and the House Rabbit Society says unaltered rabbits generally cannot be bonded safely. Allow time for healing and for hormones to settle. Advice on the wait varies: the House Rabbit Society says at least two full weeks after surgery, Wood Green says a few weeks, and all agree a newly neutered male can still father kits for a while. Keep a castrated male away from an unspayed female for up to six weeks, as the Rabbit Welfare Association advises. Our guide to neutering and spaying rabbits covers ages, aftercare and what changes.

How to bond two rabbits, step by step

This is the slow, safe method the RSPCA, the Rabbit Welfare Association and Wood Green all describe, combined into one routine.

1. Health check both rabbits. See a rabbit-savvy vet for vaccinations, a parasite check and a chat about worming. The Rabbit Welfare Association also suggests testing or treating both for the parasite E. cuniculi before they mix.
2. Neuter and wait. Neuter both and wait at least two weeks after surgery, longer for a male who will meet an unspayed female.
3. Live side by side. Put them in neighbouring enclosures split by a mesh divide at least 90 cm (3 ft) tall. Wood Green suggests a double divide with a small gap so they cannot nip through it.
4. Swap scents. After a few days, swap litter trays and used bedding daily, or stroke one rabbit with a cloth and then the other.
5. Pick a neutral space. Choose a room or pen neither rabbit has used, cleaned well. The RSPCA says it should be smaller than their final home. Lay towels or blankets for grip, scatter hay, greens and nuggets, and leave out hides and toys at first.
6. Meet together. Put both rabbits down at the same moment and step back. Stay right there, wear sturdy shoes and keep a towel ready, but do not hover over them.
7. Keep it short, then build. Start with very short sessions and end before tension rises. The House Rabbit Society suggests at least 20 minutes of work a day. Add time as they relax.
8. Add the extras. When they eat side by side calmly, add two of everything: hides with two doors, water bowls, hay piles and litter trays.
9. Move in together. Clean their permanent home thoroughly first. Leave them alone together only once they groom each other and lie side by side.

Wood Green offers a faster alternative for confident owners: mixing in a neutral pen over a weekend, staying with the pair for most of the day and leaving them together overnight if all goes well, then enlarging the pen one panel at a time every day or two. It works well, but it needs a second person and a whole weekend.

Rabbit bonding behaviour: what is normal

A fair amount of rough-looking behaviour is normal while two rabbits work out who is in charge. One rabbit is usually dominant, and that should not mean aggressive. These are all normal in the early days:

• Brief chasing that fades quickly, with the chased rabbit running rather than fighting back
• Mounting, which the other rabbit accepts or hops away from
• Small tufts of fur on the floor
• Circling, chinning things and dropping droppings to mark territory
• Ignoring each other, or sitting at opposite ends of the pen
• One rabbit lowering its head to ask for grooming
• Grooming each other's faces, eating side by side and flopping together

Wood Green gives a rough timeline for a weekend mix: by the end of day one, calm sitting at opposite ends or eating; by day three, sitting close and grooming. Head-lowering followed by licking is the sign you are waiting for. Our guide to rabbit behaviour and body language explains the signals in more detail.

Signs bonding is not working

Separate the rabbits straight away, using a towel or board and not your hands, if you see any of these:

• Charging or lunging with ears flat back
• Standing up and boxing
• Persistent fast circling or chasing where both rabbits fight
• Bites to the back that send clumps of fur flying, or kicks to the belly
• Biting that makes a rabbit scream
• Repeated mounting with biting at the head or face

Wood Green says these on day one or early day two mean the pairing is unlikely to work. The Rabbit Welfare Association calls rabbits "surprisingly vicious fighters" and advises separating too early rather than too late. After a real fight, go back to side-by-side living and ask a rabbit rescue for advice; some pairs never bond, and a different partner is kinder than forcing it. Take any bite wound to a vet.

What hutch do two rabbits need?

Two rabbits need a living space of at least 3 x 2 x 1 m (10 x 6 x 3 ft), shelter and run together, open day and night. A rabbit hutch for two rabbits is only the bedroom part of that: the Rabbit Welfare Association says the sleeping area should be at least 1.8 x 0.6 x 0.6 m (6 x 2 x 2 ft), joined to a run so the pair can come and go whenever they like. A single rabbit needs exactly the same space, since it should not be alone.

For the best rabbit hutch for two rabbits, look for these features:

• Inside floor at least 180 x 60 cm (6 x 2 ft), measured inside, not outside
• Tall enough for both rabbits to sit up without their ears touching the roof
• Room for two hides or one large bed area both can share, with two ways out
• A permanent opening into a run of at least 240 x 180 x 90 cm (8 x 6 x 3 ft)
• Solid, non-slip floors, never wire
• Raised off the ground, waterproof roof and heavy-gauge welded mesh

Our guide to rabbit hutch size goes through each measurement, and our pick of rabbit cages and pens shows setups that meet them.

Are two-tier or two-storey rabbit hutches good for two rabbits?

Only if the ground floor alone is big enough. The Rabbit Welfare Association is clear that the upper floor of a two-storey hutch, ramps, raised platforms and tunnels do not count towards a rabbit's minimum floor space. Rabbits run along the ground, so a tall, narrow two-tier hutch fails the test even when its total area looks generous.

A second level is still a nice extra on top of enough floor space. Bonded pairs often use a platform as a lookout. Two rules make a two-level rabbit hutch or two-tier indoor rabbit cage safe for a pair: the ramp must be wide and gentle enough that one rabbit cannot block the other in, and the top level needs an exit so neither rabbit is cornered. Cover slippery ramps with a mat or carpet offcut for grip.

Bedding for a newly bonded pair

Use dust-free hay or soft straw to sleep on, over a base of paper or wood pellets. Wood Green keeps some used hay when cleaning during bonding, so the shared scent stays. Softwood shavings for rabbits are where advice splits: the Rabbit Welfare Association accepts good-quality, kiln-dried shavings used with care in a well-aired space, while other rabbit groups advise against pine because of its aromatic oils. We'd skip pine and cedar altogether. Our rabbit bedding guide compares every option.

After bonding: keeping the pair together

Keep a bonded pair together for life wherever you can. The Rabbit Welfare Association advises taking both to the vet in one carrier, because they comfort each other, and the San Francisco House Rabbit Society says to keep pairs together even after surgery unless separation is truly needed. Wood Green suggests waiting a couple of weeks after moving into their permanent home before giving free-roam time, starting with a few minutes a day.

Give them space and two of everything, and keep their routine steady. For the basics of building trust with you as well as each other, see our guide to taming and handling a rabbit, and for everything else, our complete rabbit care guide.
