Read on to unlock the secrets of peaceful cohabitation, so your rabbits can live happily ever after instead of fighting to the bitter end!

Why Rabbits Attack Each Other

Rabbits are naturally territorial animals and can be quite aggressive towards other rabbits, especially ones they don't know. There are several reasons rabbits may attack or fight with each other:

Establishing Dominance

When rabbits first meet, they will often fight to establish a dominance hierarchy. This helps determine which rabbit will be the 'alpha' and have primary access to resources like food, water, and prime sleeping areas. The less dominant rabbit will usually back down after a few skirmishes, accepting their place lower in the hierarchy.

Competition for Mates

During breeding season, male rabbits become very territorial and aggressive as they compete for the right to mate with females. Unneutered males will viciously fight other males to prove they are the most fit suitor. They will also harass and try to mate with any unspayed females.

Protecting Resources

Rabbits are highly protective of their food, water, shelter, litterboxes, and sleeping areas. If another rabbit approaches, the territorial rabbit may attack to drive them away and defend their resources. This is especially common if resources are limited.

Protecting Young

Mother rabbits (does) can be very aggressive while raising a litter of kits. They will attack any rabbit or predator that approaches the nest. Mother and baby bonds are very strong, and does will fiercely defend their young.

Guarding Territory

In the wild, rabbits establish warrens and tunnel systems which they defend from intruders. Domestic rabbits retain this territorial instinct and will attack other rabbits that enter their space. Free-roaming unneutered rabbits are especially prone to fighting over territory.

Redirected Aggression

Sometimes rabbits lash out due to frustration or fear, attacking a bonded mate who is not the actual source of their anxiety. This redirected aggression usually occurs when rabbits feel threatened by predators or loud noises.

So in summary, the main triggers for rabbit fights are hierarchy disputes, mating competition, resource guarding, maternal protection, territorialism, and redirected aggression. Their natural instincts drive them to battle others to establish dominance, breed, and protect their resources and kits. Spaying/neutering is key to reducing hormonal aggression.

Two Unneutered Male Rabbits Fighting to the Death

When two unneutered (intact) male rabbits are placed together, deadly fighting is unfortunately a very real possibility. In the wild, the males have large roaming territories and do not often come into contact. But in captivity, they are forced into close quarters and will fight fiercely.

Several factors contribute to the violence and potential mortality:

Surging Testosterone

Intact males have very high testosterone levels which makes them territorial, aggressive, and ready to fight. They lack the hormonal modulation created by neutering. This fuels their vicious battle for dominance.

Breeding Competition

In the wild breeding season, bucks will kill competing males to secure their right to sire young. They have a biological drive to eliminate rivals and be the sole breeder. Without neutering, this remains strong.

Limited Space

Confined in a hutch or pen, the rabbits cannot escape each other. In the wild they would run away and establish distinct territories. The forced proximity intensifies the fights.


Rabbits have extremely sharp claws and teeth, powerful hind legs, and muscular necks. They are well-equipped to cause severe injuries during battle. A rabbit's claws can easily eviscerate a rival.

No Humane Intervention

Unlike wild territory disputes which end when one retreats, domestic rabbits are trapped together and will battle to the death. Without a human to swiftly separate them, the dominant rabbit will continue attacking the submitting one.

High Pain Tolerance

Due to their strong prey drive, rabbits can keep fighting even when injured. Adrenaline allows them to ignore pain and damage. By the time exhaustion sets in, it may be too late.

So when two unaltered male rabbits are placed together, their raging hormones, mating drive, confined space, deadly weapons, high pain tolerance, and lack of escape all create a perfect storm for a fight ending in death. At minimum, severe injuries are almost guaranteed.

Neutering is absolutely vital to avoid this deadly outcome. It calms the violent territorial and mating instincts. Spaying females also reduces territorial aggression between does. Sterilization lets rabbits coexist peacefully.

Two Female Rabbits Fighting to the Death

Female (doe) rabbits are just as capable of vicious fights as males when competing over territory, hierarchy status, or resources. However, deadly combat is less likely for a few reasons:

Lower Testosterone

Female rabbits have minimal testosterone compared to males. This male hormone fuels extreme aggression. So does tend to be less likely to have a battle ending in death.

No Mating Competition

Without raging hormones compelling them to kill rivals to secure the right to breed, females are less likely to fatally attack each other. They do not get the same mating drive boost to aggression.

Less Muscle Mass

On average, does have less sheer body mass and muscle than males. So they can't inflict the same amount of traumatic damage on each other during fights.

Maternal Not Mating Focus

Unspayed females spend more energy defending kits and establishing nests than competing for mates. So they direct aggression toward protecting offspring rather than male-driven violence.

However, female rabbits can and will attack each other viciously over territory, food, water, housing, and sleeping areas. They are still capable of causing severe injuries with claws, teeth, and kicks. Bloody wounds, ripped out fur, deep punctures, lost eyes, broken bones, and deadly trauma can occur in doe-to-doe combat.

Females may also redirect aggression toward a bonded partner due to anxiety. And mothers may attack any perceived threat to their kits.

So female-female fights can certainly turn deadly in some cases, just less frequently than male-male battles. Spaying reduces territorial hormonal aggression in females, allowing peaceful cohabitation. Proper resources and space also help minimize competition and attacks between does.

Male Rabbit Fighting Female Rabbit to the Death

While male-female rabbit fights are most typically associated with breeding behavior, they can on occasion turn violent and potentially fatal. This usually only occurs if the rabbits are not sterilized. Reasons a male may attack a female to the death include:

Spurned Breeding Attempt

If an unspayed female rejects the advances of an unneutered male, he may become enraged and attack her for denying him mating rights. His surging testosterone and mating drive fuels violence against the non-receptive doe.

Forced Mating

An aggressive buck may try to force himself on a female whether she is receptive or not. The female will fight back to avoid the unwanted breeding, and the male may brutally attack in an attempt to overpower her.

Competition For Another Mate

A pair of rabbits may be bonded, but when a new doe is introduced, the male may suddenly turn on his former partner if she blocks him from accessing the new female. The banned breeding access can turn him violent.

Interloper In Territory

Even neutered males may attack an unfamiliar spayed female placed in their space. The male rabbit views the stranger as an invading threat, prompting brutal eviction attempts up to the point of death.

Maternal Protection

A mother doe will fiercely fight any rabbit trying to disturb her nest, even the father of the kits. If the male insists on entering the nesting area, the mother may battle him with lethal force to protect her young.

So while rare in fixed rabbits, male-female skirmishes can turn fatal if driven by breeding instincts, competition, territorialism, or maternal protection in unaltered rabbits. Proper bonding, spacing, sterilization, and intervention is key to maintaining harmony.

Are My Rabbits Fighting Or Playing?

It can sometimes be hard to tell the difference between normal active playfighting in rabbits versus true aggression requiring intervention. Here are some signs it’s play versus a real fight:


  • Both rabbits take turns chasing each other.

  • Brief nips and kicks without sustained biting/scratching.

  • No loud screeching or aggression sounds.

  • Both rabbits sometimes mount each other.

  • Neither rabbit retreats to a corner for safety.

  • Ears remain upright, not pinned back against neck.

  • After a pause, they come back for more playing.

  • Fur remains sleek and unruffled on both rabbits.

True Fighting

  • One rabbit chases the other persistently.

  • Biting and scratching are intense, drawn-out, and injurious.

  • Loud shrieking, growling, grunting sounds of aggression.

  • The losing rabbit screams in pain and tries to flee or hide.

  • The dominant rabbit's ears are pinned back flat against the neck.

  • Tufts of fur from violent biting are ripped out leaving bald patches.

  • The losing rabbit appears injured, shaken, or withdrawn after the fight.

So in summary, playfighting is a fairly even exchange without real injuries. True fighting shows clear victim and aggressor roles, real trauma, and fearful withdrawal by the losing rabbit. If blood is drawn, screaming heard, or fur tufts fly, intervene immediately to prevent potential death.

Acceptable Behavior in Rabbits

It’s normal and acceptable for rabbits kept together to show these behaviors:

  • Sitting or resting side-by-side

  • Eating together amicably

  • Grooming each other

  • Touching noses affectionately

  • Circling closely without biting

  • Mounting attempts not followed by aggression

  • Brief bouts of playful chasing and nipping

  • Small scuffles resolving without injury

  • Equal give-and-take interactions

  • Sharing resources like food bowls and litter boxes

  • Little to no screeching, growling, or distressed sounds

These behaviors show peaceful bonding, playing, and accepted hierarchy between rabbits. No intervention is needed for normal acceptable activities that do not escalate to harmful aggression. Bonding pairs may take months to fully establish positive relations.

Unacceptable Behavior in Rabbits

These behaviors are abnormal and unacceptable, often indicating true aggression:

  • Lunging with intent to bite and scratch

  • Prolonged vicious biting leading to wounds

  • Tufts of fur being ripped out

  • High-pitched screeching indicating pain or fear

  • Pressing belly to the ground in terror

  • Prolonged chasing without pausing

  • Mounting attempts accompanied by biting or fur pulling

  • Inability to retreat from attacks

  • Loss of appetite, engagement, or activity after fights

  • Injuries such as cuts, punctures, limping, or eye damage

  • Lack of intervention by human allowing harm to continue

Any time blood is drawn, flesh punctured, or high-pitched screaming emitted, you must immediately separate the rabbits. Seek veterinary care if wounds are severe or persist. Ongoing behavior like this is unacceptable as it causes physical and psychological damage. Rabbits forced to continually live in stress and fear often die early from the condition.

What To Do If Rabbits Start Fighting

If your rabbits start showing signs of hostility like lunging, biting, screeching, or fur pulling do not just stand by. You must take action right away to prevent potential death. Here are the steps to take:

Don’t Ignore the Fight

Never assume “they’ll just work it out.” Serious injuries or death can occur in minutes if a real fight starts. So remain attentive and do not leave them alone together during the spat.

Make a Loud Noise

A sharp loud clap or shout can sometimes startle fighting rabbits apart for a moment. This may pause the brawl long enough to intervene. However, be prepared to take the next step if noise does not deter them.

Separate Them Immediately

As soon as aggression starts, physically remove one rabbit and place it in a separate carrier away from the other. Use thick gloves to protect your hands and arms. Be very cautious separating two rabbits intent on harming each other.

Assess Your Rabbits for Injuries

Look both rabbits over closely for any wounds, limping, bleeding, fur loss, or trauma. Even if you do not see external injury, stress can cause internal damage. Take injured rabbits to the veterinarian promptly for care.

Keep Your Rabbits Separated

Do not reintroduce the pair until you identify and remedy the source of hostility. Keep their enclosures far apart so they cannot see or hear each other which could provoke more aggression. Allow a lengthy cooling off period.

Separate Rabbits with Fencing

If forced by space limitations to house recently combative rabbits in adjoining pens, use solid barriers not wire mesh fencing between them. Being able to see one another can perpetuate hostility and should be avoided while working to re-bond the pair.

What To Do If Rabbits Injure Each Other While Fighting

If your rabbits sustain injuries while fighting, here are the steps to properly care for them:

Assess the Severity

Look over all wounds carefully to determine their extent. Loss of fur, limping, cuts, punctures, and bleeding should be noted. Judge if emergency veterinary care is needed for deep gashes, internal damage, or eye/nose/ear trauma.

Stop Bleeding

Press clean cloths or gauze pads over wounds firmly to halt bleeding. Apply styptic powder or cornstarch if available. Do not use products like alcohol or peroxide which can damage tissue. Seek professional medical care for uncontrolled bleeding.

Clean Wounds

Flush wounds with sterile saline to remove debris. Do not apply ointments which can cause chemical irritation. Bactine spray can be used lightly to ease pain. Hydrogen peroxide will damage exposed tissue and should only be used on sealed scabs.

Protect Injuries

Cover wounds with sterile non-stick gauze or bandages. Wrap injured body parts with vet wrap to limit movement and prevent re-injury. Change dressings daily to check healing. Get e-collars to keep rabbits from chewing off bandages.

See the Veterinarian

Make an appointment as soon as possible for examination and care of any significant or persistent wounds, limping, eye damage, or unexplained lethargy. Follow all instructions for medications, diet, and activity restriction.

Separate Rabbits

Keep the injured rabbits fully isolated in recovery until healed. Monitor their interactions closely post-recovery to prevent re-aggression. Any ongoing hostility may mean permanently separating the pair for health and safety. Have patience introducing them again slowly post-injury.

How To Stop Your Rabbits Fighting

To curb fighting long-term and allow your rabbits to safely co-exist follow these steps:


Get both rabbits sterilized to eliminate hormonal territorial and mating competition aggression between them. This is imperative for harmony.

Proper Introduction

Re-introduce the pair very slowly post-conflict to rebuild positive relations. Switch their spaces to redistribute scents and establish neutral territory.

Stress Reduction

Reduce environmental stressors like loud noise, changes, unfamiliar people, or new pets that may be triggering aggressive behavior.

Ample Resources

Ensure rabbits have sufficient food, water, housing, litter boxes, hiding spots, and toys so they don’t have to compete over these items as limited resources.

Monitor Interactions

Keep a very close eye on their behaviors when reunited after any incident. Separate immediately if aggression resurfaces. You may need professional mediation.

Proper Handling

Pick up each rabbit properly supporting all feet and never by the ears. Holding rabbits incorrectly can injure them or provoke bites.


Work on clicker training each rabbit or teaching commands like “come” to interrupt potential chasing before it escalates into combat. Redirect energy into learning.

Veterinary Guidance

Seek guidance from an experienced rabbit veterinarian, especially if aggression problems persist despite all efforts. Some personalities may be fundamentally incompatible.

With vigilance, spay/neuter surgeries, environmental adjustments, slow re-introductions, training, and medical guidance, most pairs can learn to coexist peacefully. Consistency, time, and patience are needed to resolve rabbit conflicts without fatal consequences.
