What Does Rabbit Mounting Mean?

Rabbit mounting, also known as rabbit humping, refers to when one rabbit climbs on top of another rabbit and thrusts their hips. This is a common behavior in rabbits that serves several purposes. Mounting is part of the rabbit mating ritual, allowing the male rabbit to intromit and inseminate the female. However, rabbits also mount each other for non-sexual reasons. Mounting establishes dominance and hierarchy within rabbit groups. It can also be a play behavior in younger rabbits. Mounting is a normal rabbit behavior but excessive mounting may indicate a behavioral issue that needs addressing.

The rabbit doing the mounting is asserting their dominance over the mounted rabbit. In the wild, rabbits live in large social groups with complex social structures. Mounting allows them to establish rankings within their group. The alpha rabbit, usually a male, will mount the other rabbits to display his dominance. Female rabbits may also mount each other to establish dominance, although this is less common.

In domestic rabbits, mounting helps establish the social order in a home with multiple rabbits. The dominant rabbit will mount the submissive rabbits. Neutering and spaying rabbits reduces but does not eliminate mounting behaviors. Even altered rabbits will mount to show dominance. Occasional mounting is usually harmless but repeated, excessive mounting can be a symptom of bullying.

Mounting is also part of the rabbit courtship and mating process. An unneutered male rabbit will mount a female as part of the mating ritual. Multiple mounts may occur before actual intromission or mating takes place. The male grips the female's fur with his teeth to stabilize himself during the mount. Mating follows successful mounting with the male thrusting to achieve intromission.

In young rabbits, mounting is often a social play behavior. Young rabbits, especially siblings from the same litter, will playfully mount each other while running and jumping. Play mounting establishes bonds and social standing. As rabbits age, the mounting takes on more social and sexual significance.

In summary, rabbit mounting is a multifunctional behavior related to dominance, play, and reproduction in rabbits. It helps rabbits organize their social structures. Mounting is normal rabbit behavior but excessive mounting may indicate issues like harassment, lack of neutering, or poor socialization.

Why Do Rabbits Hump Each Other?

Rabbits hump or mount each other for several reasons:

  • To establish dominance and social hierarchy
  • As a mating behavior for breeding purposes
  • As a play behavior, especially in younger rabbits
  • To show excitement or gain attention
  • Due to hormonal influences if the rabbit is not neutered/spayed

Dominance is one of the most common reasons rabbits mount. In the wild, rabbits live in large social groups and need to establish a clear social order. The alpha rabbit, usually a male, will mount the other rabbits to display his dominance. Female rabbits may also mount to show dominance.

Intact male rabbits mount females as part of the breeding process. Multiple mounts occur before mating is successful. The male rabbit needs to mount properly to achieve intromission and impregnate the female. Even neutered males may try to mount due to residual hormonal influences.

Younger rabbits often mount each other as a form of social play. They chase each other around mounting and nipping. Play mounting helps young rabbits bond and establish their place in the group. It is a harmless behavior in younger rabbits.

Excitement and attention-seeking can also spark mounting behaviors. The motion of mounting provides stimulation. A bored, under-exercised rabbit may mount inanimate objects or other rabbits simply to gain some excitement and interaction. This is most common in unneutered males.

Lastly, hormonal influences from lack of neutering are a key reason for mounting in domestic rabbits. Intact male rabbits in particular will be strongly compelled to mount due to sexual hormones. Spaying or neuteringrabbits helps reduce the frequency of mounting behaviors.

In summary, the reasons rabbits mount each other include social hierarchy, breeding/mating, play, excitement, and hormones from lack of neutering. While often harmless, excessive mounting can indicate issues like harassment, breeding urges, or poor socialization.

Rabbit Mounting and Biting Behavior

When rabbits mount each other, they will often grasp the fur of the mounted rabbit with their teeth. This biting behavior serves several purposes:

  • Stability – The bite provides stability and leverage for the mounted position
  • Dominance – Biting establishes the hierarchy between dominant and submissive rabbit
  • Female cooperation – Female rabbits remain still and cooperate with mating by allowing the neck bite
  • Courtship communication – Gentle biting communicates intent between mating rabbits
  • Correction – The dominant rabbit may bite harder to correct unwanted behavior

Without the stabilizing teeth grip, it would be difficult for the mounting rabbit to balance during the thrusting motion. The bite gives them leverage and control over the mounted rabbit's movements. In the wild, dominant rabbits may bite the neck fur of subordinates to discipline them. The bite also communicates sexual intent between potential mates.

Female rabbits tend to tolerate the bite as it allows them to cooperate during mating. If they struggle or bolt, mating will be unsuccessful so they allow the neck grip. However, the biting also establishes the male rabbit as dominant. Excessive biting with wounds indicates harassment or aggression rather than appropriate mating behaviors.

In non-sexual mounting between rabbits establishing hierarchy, the bite grip reinforces the dominance of the mounting rabbit over the submissive rabbit. Even gentle play mounting in young rabbits involves a bite as they experiment with dominant and submissive roles. The dominant rabbit may correct unwanted behaviors with a firmer bite.

While biting during mounting provides stability and communicates social roles, excessive biting should be discouraged. Wounds or fur loss from forceful bites indicates bullying or aggression. Removing the aggressor rabbit and providing distraction objects can help target misplaced biting behaviors. With patience and training, rabbits can learn to moderate their biting during mounting interactions.

Why Do Female Rabbits Hump Each Other?

Female rabbits sometimes mount and hump other females as an expression of dominance. While less common than male mounting behaviors, female-female mounting establishes hierarchy and social order within all-female domestic rabbit groups. Reasons female rabbits mount each other include:

  • Establishing dominance/submission – The lead female rabbit mounts to display her high status over more submissive rabbits.

  • Access to resources – The dominant rabbit may mount to assert her priority access to food, water, shelter, litter boxes, or other valued items.

  • Territoriality – Mounting reinforces territorial boundaries between neighboring female rabbits.

  • Correction – The dominant female will mount subordinates to correct unwanted behaviors or keep them in line.

  • Play behavior – Young females may mount littermates playfully to practice adult social behaviors.

  • False pregnancy – A pseudopregnant female rabbit may mount or display other masculine behaviors.

  • Confusion – In same-sex groups, mounting may occur due to confusion over mate identity.

The frequency of female-female mounting decreases if the rabbits are spayed. However, even spayed females may mount due to dominance conflicts or territorial disputes. Personality also influences mounting behaviors. Naturally dominant females are more likely to mount frequently.

If mounting leads to injuries, fur loss, or constant harassment of submissive rabbits, separating the dominant aggressor is recommended. Additional resources like food bowls, litter boxes, or hiding places can also ease competition. Mounting between females should be moderated but is generally normal rabbit social behavior.

Why Do Two Male Rabbits Hump Each Other?

When two male domestic rabbits mount each other, it is primarily an expression of dominance and territory marking. Mounting establishes hierarchy between the males and communicates territorial boundaries. Reasons for intermale mounting include:

  • Establishing an alpha/beta hierarchy – The dominant male mounts the subordinate male to display higher status.

  • Territorial marking – Mounting sends scent cues to mark territory boundaries between males.

  • False pregnancy – A pseudopregnant male rabbit may act territorial and mount other males.

  • Confusion – Same-sex mounting may occur if the rabbits are confused over mate identity.

  • Play behavior – Young males may mount each other while playing to establish future social roles.

  • Correction – The dominant male may mount subordinates to correct unwanted behaviors.

  • Sexual behavior – Less common but males may mount males for homosexual pair bonding.

Mounting between males decreases after neutering due to reduced hormones and territorial urges. However, neutered males may still mount each other to express dominance. Some mounting during play or sorting out hierarchy roles is normal. But persistent, forceful mounting should be discouraged to prevent injuries.

Providing adequate space, resources, and distractions can ease male-male competition. Separating bullying males may be necessary. Homosexual mounting between bonded male pairs may also occur, especially if neutered at an older age. As long as there is no aggression, bonding behavior between males is fine.

What Is Backwards Mounting In Rabbits?

Backwards mounting refers to when a rabbit turns around and mounts another rabbit with their back end facing forward. This is sometimes seen between bonded rabbit pairs as a display of affection and mate guarding behavior. Reasons rabbits may backwards mount include:

  • Mate guarding – Rabbits will guard bonded mates by mounting backwards to block other advances.

  • Affectionate mounting – Backwards mounting shows care between bonded pairs.

  • Establishing bonds – It helps new pairs connect by mounting in a non-threatening way.

  • Soliciting grooming – The forward-facing rabbit can request grooming from the mounted rabbit.

  • Play behavior – Backwards mounting may occur during play chasing and interaction.

  • Establishing dominance – Less common but can establish rank between a pair.

  • False pregnancy – A pseudopregnant rabbit may display backwards mounting urges.

Unlike forward mounting, backwards mounting is rarely forceful or aggressive. The gentle hip thrusting does not penetrate. It communicates affection and shows protective mate guarding behaviors. Backwards mounting helps new pairs bond and solicits social grooming.

Neutering typically reduces backwards mounting in males but does not always eliminate it. Some bonded rabbits continue to backwards mount regularly due to habit or playfulness. As long as there is no biting or fur loss, backwards mounting is generally a harmless bonding behavior. It should not be confused with aggressive forward mounting seen between unfamiliar rabbits.

Neutered Male Rabbit Still Mounting

It's common for a neutered male rabbit to still display some mounting behaviors even after castration surgery. Neutering reduces but does not always eliminate a rabbit's urge to mount for several reasons:

  • Residual hormones – The rabbit still has low levels of hormones influencing his behavior.

  • Established habits – The rabbit is accustomed to mounting from before he was neutered.

  • Dominance displays – The rabbit may still mount to show dominance over other rabbits.

  • Territorial marking – The neutered male may still feel a need to mark his territory.

  • Attention-seeking – Mounting gets a reaction and attention from people or other rabbits.

  • False pregnancy – In rare cases, neutered males display pseudopregnancy behaviors.

  • Play behavior – Mounting remains a common play behavior in young neutered males.

  • Learned behavior – Mounting has become a learned and reinforced behavioral pattern.

As long as the mounting is not excessive, forceful, or causing injuries, it can be considered normal for a neutered male. However, any aggression, biting, fur loss, or distress in the mounted rabbit needs to be addressed. Additional reinforcement training can help further reduce mounting behaviors. Separating the mounting rabbit if needed and providing distraction toys is also recommended in problem cases.

Should You Stop Rabbits from Mounting?

In general, mild mounting behavior should not be stopped as it is a normal social expression in rabbits. However, forceful, aggressive, and excessive mounting should be discouraged to prevent injuries. Here are some guidelines on when to intervene in mounting behaviors:

  • Mounting causes wounds, fur loss, or distress – Immediately separate rabbits and address the aggression.

  • Persistent mounting after neutering – Continue reinforcing neutering with training; may need to separate.

  • Mounting prevents access to food, water or housing – Add resources to ease competition.

  • Constant mounting by dominant rabbit – Separate the bullying rabbit or remove to a new group.

  • Mounting side-by-side rabbits – Gently discourage mounting rabbits already bonded.

  • Mounting indiscriminate objects – Redirect to appropriate toys to prevent over-arousal.

  • Mounting linked to false pregnancy – Add environmental enrichment; see a vet if severe.

  • Excessive mounting multiple times daily – Neuter male rabbits and reinforce training.

With patience and training, rabbits can learn appropriate mounting behaviors and social skills. The goal should be to moderate mounting, not eliminate it completely. Some mounting helps establish normal social bonds and hierarchy. Only problematic mounting that causes harm requires intervention. Learning proper rabbit social behaviors takes time.


In summary, mounting is a normal multifunctional social behavior in rabbits. It establishes dominance and hierarchy, facilitates courtship and mating, and occurs during play interactions. Mounting is often accompanied by a stabilizing neck bite. While mounting is a natural behavior for rabbits, excessive or forceful mounting can indicate issues like harassment, lack of neutering, or poor socialization. With training and reinforcement, rabbit mounting behaviors can be kept to healthy levels and serve the useful social purposes for rabbit groups. Monitoring mounting behaviors provides insight into the social dynamics between rabbits.
