Rabbits are small mammals in the family Leporidae (which also includes the hares), which is in the order Lagomorpha (which also includes pikas). They are familiar throughout the world as a small herbivore, a prey animal, a domesticated form of livestock, and a pet, having a widespread effect on ecologies and cultures. The most widespread rabbit genera are Oryctolagus and Sylvilagus. The former, Oryctolagus, includes the European rabbit, Oryctolagus cuniculus, which is the ancestor of the hundreds of breeds of domestic rabbit and has been introduced on every continent except Antarctica. The latter, Sylvilagus, includes over 13 wild rabbit species, among them the cottontails and tapetis. Wild rabbits not included in Oryctolagus and Sylvilagus include several species of limited distribution, including the pygmy rabbit, volcano rabbit, and Sumatran striped rabbit.

Rabbits are a paraphyletic grouping, and do not constitute a clade, as hares (belonging to the genus Lepus) are nested within the Leporidae clade and are not described as rabbits. Although once considered rodents, lagomorphs diverged earlier and have a number of traits rodents lack, including two extra incisors. Similarities between rabbits and rodents were once attributed to convergent evolution, but studies in molecular biology have found a common ancestor between lagomorphs and rodents and place them in the clade Glires.

Rabbit physiology is suited to escaping predators and surviving in various habitats, living either alone or in groups in nests or burrows. As prey animals, rabbits are constantly aware of their surroundings, having a wide field of vision and ears with high surface area to detect potential predators. The ears of a rabbit are essential for thermoregulation and contain a high density of blood vessels. The bone structure of a rabbit's hind legs, which is longer than that of the fore legs, allows for quick hopping, which is beneficial for escaping predators and can provide powerful kicks if captured. Rabbits are typically nocturnal and often sleep with their eyes open. They reproduce quickly, having short pregnancies, large litters of four to twelve kits, and no particular mating season; however, the mortality rate of rabbit embryos is high, and there exist several widespread diseases that affect rabbits, such as rabbit hemorrhagic disease and myxomatosis. In some regions, especially Australia, rabbits have caused ecological problems and are regarded as a pest.

Humans have used rabbits as livestock since at least the first century BC in ancient Rome, raising them for their meat, fur and wool. The various breeds of the European rabbit have been developed to suit each of these products; the practice of raising and breeding rabbits as livestock is known as cuniculture. Rabbits are seen in human culture globally, appearing as a symbol of fertility, cunning, and innocence in major religions, historical and contemporary art.

Terminology and etymology

The word rabbit derives from the Middle English {{lang|enm|rabet}} ("young of the coney"), a borrowing from the Walloon {{lang|wa|robète}}, which was a diminutive of the French or Middle Dutch {{lang|dum|robbe}} ("rabbit"), a term of unknown origin. The term coney is a term for an adult rabbit used until the 18th century; rabbit once referred only to the young animals.{{OEtymD|coney|accessdate=2024-09-17}} More recently, the term kit or kitten has been used to refer to a young rabbit.{{cite journal|last1=Zapletal|first1=D.|last2=Švancarová|first2=D.|last3=Gálik|first3=B.|year=2021|title=Growth of suckled rabbit kits depending on litter size at birth|journal=Acta Fytotechnica et Zootechnica|volume=24|issue=1|pages=55–59 |doi=10.15414/afz.2021.24.01.55-59|doi-access=free | issn=1335-258X }}{{cite journal |last1=Booth |first1=J.L. |last2=Peng |first2=X. |last3=Baccon |first3=J. |last4=Cooper |first4=T.K. |year=2013 |title=Multiple complex congenital malformations in a rabbit kit (Oryctolagus cuniculi) |journal=Comparative Medicine |volume=63 |issue=4 |pages=342–347 |pmc=3750670 |pmid=24209970}} The endearing word bunny is attested by the 1680s as a diminutive of bun, a term used in Scotland to refer to rabbits and squirrels.{{OEtymD|bunny|accessdate=2024-10-21}}

Coney is derived from cuniculus, a Latin term referring to rabbits which has been in use from at least the first century BCE in Hispania. The word cuniculus may originate from a diminutive form of the word for "dog" in the Celtic languages.{{Cite journal |last1=Ballester |first1=X. |last2=Quinn |first2=R. |date=2002 |title=Cuniculus 'Rabbit' — A Celtic Etymology |url=http://www.continuitas.org/texts/ballester_cuniculus.pdf |journal=World Rabbit Science |volume=10 |issue=3}}

Taxonomy and evolution

Rabbits and hares were formerly classified in the order Rodentia (rodents) until 1912, when they were moved into the order Lagomorpha (which also includes pikas). Since 1945, there has been support for the clade Glires that includes both rodents and lagomorphs,{{Citation |last=Korth |first=William W. |title=Classification of Rodents |date=1994 |work=The Tertiary Record of Rodents in North America |series=Topics in Geobiology |volume=12 |pages=27–34 |editor-last= |editor-first= |url=https://link.springer.com/chapter/10.1007/978-1-4899-1444-6_4 |access-date=2024-09-16 |place=Boston, MA |publisher=Springer US |language=en |doi=10.1007/978-1-4899-1444-6_4 |isbn=978-1-4899-1444-6|url-access=subscription }} though the two groups have always been closely associated in taxonomy; fossil,{{Cite journal |vauthors=Asher RJ, Meng J, Wible JR, etal |title=Stem Lagomorpha and the antiquity of Glires |journal=Science |volume=307 |issue=5712 |pages=1091–4 |date=February 2005 |pmid=15718468 |doi=10.1126/science.1107808 |bibcode=2005Sci...307.1091A |s2cid=42090505 }} DNA,{{Unbulleted list citebundle|{{Cite journal |vauthors=Madsen O, Scally M, Douady CJ, etal |title=Parallel adaptive radiations in two major clades of placental mammals |journal=Nature |volume=409 |issue=6820 |pages=610–4 |date=February 2001 |pmid=11214318 |doi=10.1038/35054544|bibcode=2001Natur.409..610M |s2cid=4398233 |ref=none}}|{{Cite journal |vauthors=Murphy WJ, Eizirik E, Johnson WE, Zhang YP, Ryder OA, O'Brien SJ |title=Molecular phylogenetics and the origins of placental mammals |journal=Nature |volume=409 |issue=6820 |pages=614–8 |date=February 2001 |pmid=11214319 |doi=10.1038/35054550|bibcode=2001Natur.409..614M |s2cid=4373847 |ref=none}}}} and retrotransposon studies in the 2000s have solidified support for the clade.

The extant species of family Leporidae, of which there are more than 70, are contained within 11 genera, one of which is Lepus, the hares. There are 32 extant species within Lepus. The cladogram is from Matthee et al., 2004, based on nuclear and mitochondrial gene analysis.{{cite journal |last1=Matthee |first1=Conrad A. |display-authors=etal |date=2004 |title=A Molecular Supermatrix of the Rabbits and Hares (Leporidae) Allows for the Identification of Five Intercontinental Exchanges During the Miocene |journal=Systematic Biology |volume=53 |issue=3 |pages=433–477 |doi=10.1080/10635150490445715 |pmid=15503672 |doi-access=free}}

The term rabbit is typically used for all Leporidae species, excluding the genus Lepus. Members of that genus are known as hares{{sfn|Alves|Ferrand|Hackländer|2008|pages=1-9}} or jackrabbits.{{sfn|Varga|2013|page=3}}

Rabbits and hares have historically not occupied the same locations, and only became sympatric relatively recently; historic accounts describe antagonistic relationships between rabbits and hares, specifically between the European hare and European or cottontail rabbits, but scientific literature since 1956 has found no evidence of aggression or undue competition between rabbits and hares. When they appear in the same habitat, rabbits and hares can co-exist on similar diets.{{sfn|Alves|Ferrand|Hackländer|2008|pages=241-249}} Hares will notably force other hare species out of an area to control resources, but are not territorial.{{Sfn|Angerbjörn|Schai-Braun|2023|pp=119–219}} When faced with predators, hares will escape by outrunning them, whereas rabbits, being smaller and less able to reach the high speeds of longer-legged hares, will try to seek cover.

Descendants of the European rabbit are commonly bred as livestock and kept as pets, whereas no hares have been domesticated, though populations have been introduced to non-native habitats for use as a food source.{{sfn|Nowak|1999|pages=1733-1738}} The breed known as the Belgian hare is actually a domestic rabbit which has been selectively bred to resemble a hare,{{Cite journal |last=Lyon |first=M.

{{Main|Domestic rabbit}}

Rabbits, specifically the European rabbit (Oryctolagus cuniculus) species, have long been domesticated. The European rabbit has been widely kept as livestock, starting in ancient Rome from at least the first century BC. Selective breeding, which began in the Middle Ages, has generated a wide variety of rabbit breeds, of which many (since the early 19th century) are also kept as pets.{{cite journal|last1=Irving-Pease|first1=Evan K.|last2=Frantz|first2=Laurent A.F.|last3=Sykes|first3=Naomi|last4=Callou|first4=Cécile|last5=Larson|first5=Greger|title=Rabbits and the Specious Origins of Domestication|journal=Trends in Ecology & Evolution|volume=33|issue=3|pages=149–152|year=2018|issn=0169-5347|doi=10.1016/j.tree.2017.12.009|pmid=29454669|bibcode=2018TEcoE..33..149I |s2cid=3380288 |url=http://qmro.qmul.ac.uk/xmlui/handle/123456789/34474}} Some strains of European rabbit have been bred specifically as research subjects, such as the New Zealand white.{{cite journal |last1=Mapara |first1=M. |last2=Thomas |first2=B. |last3=Bhat |first3=K. |date=2012 |title=Rabbit as an animal model for experimental research |journal=Dental Research Journal |volume=9 |issue=1 |pages=111–8 |doi=10.4103/1735-3327.92960 |doi-broken-date=1 November 2024 |pmc=3283968 |pmid=22363373 |quote=Amongst various strains, New Zealand white strains of rabbits are commonly being used for research activities.

Carl Linnaeus originally grouped rabbits and rodents under the class Glires; later, they were separated as the scientific consensus is that many of their similarities were a result of convergent evolution. DNA analysis and the discovery of a common ancestor have supported the view that they share a common lineage, so rabbits and rodents are now often grouped together in the clade or superorder Glires.{{Cite book|editor-first1=Katherine |editor-last1=Quesenberry |editor-first2=Connie J. |editor-last2=Orcutt |editor-first3=Christoph |editor-last3=Mans |editor-first4=James W. |editor-last4=Carpenter |title=Ferrets, Rabbits, and Rodents: Clinical Medicine and Surgery |edition=4th |date=2020 |chapter=Basic Anatomy, Physiology, and Husbandry of Rabbits |pages=131–149 |first1=Thomas M. |last1=Donnelly|first2= David |last2=Vella |doi=10.1016/B978-0-323-48435-0.00011-3 |isbn=978-0-323-48435-0 }}{{Cite journal |last1=Kriegs |first1=JO |last2=Churakov |first2=G|last3=Jurka |first3=J |last4=Brosius |first4=J |last5=Schmitz |first5=J |title=Evolutionary history of 7SL RNA-derived SINEs in Supraprimates |journal=Trends in Genetics |volume=23 |issue=4 |pages=158–61 |date=April 2007 |pmid=17307271 |doi=10.1016/j.tig.2007.02.002 }}

Since speed and agility are a rabbit's main defenses against predators, rabbits have large hind leg bones and well-developed musculature. Though plantigrade at rest, rabbits are on their toes while running, assuming a more digitigrade posture.{{Cite journal |last1=Hall |first1=Patrick |last2=Stubbs |first2=Caleb |last3=Anderson |first3=David E. |last4=Greenacre |first4=Cheryl |last5=Crouch |first5=Dustin L. |date=2022-06-17 |title=Rabbit hindlimb kinematics and ground contact kinetics during the stance phase of gait |journal=PeerJ |language=en |volume=10 |pages=e13611 |doi=10.7717/peerj.13611 |doi-access=free |issn=2167-8359 |pmc=9208372 |pmid=35734635}} Rabbits use their strong claws for digging and (along with their teeth) for defense.{{cite journal |last1=d'Ovidio |first1=Dario |last2=Pierantoni |first2=Ludovica |last3=Noviello |first3=Emilio |last4=Pirrone |first4=Federica |title=Sex differences in human-directed social behavior in pet rabbits |journal=Journal of Veterinary Behavior |date=September 2016 |volume=15 |pages=37–42 |doi=10.1016/j.jveb.2016.08.072 }} Each front foot has four toes plus a dewclaw.

Most wild rabbits (especially compared to hares) have relatively full, egg-shaped bodies. The soft coat of the wild rabbit is agouti in coloration (or, rarely, melanistic), which aids in camouflage. The tail of the rabbit (with the exception of the cottontail species) is dark on top and white below. Cottontails have white on the top of their tails.{{cite encyclopedia |title=rabbit |encyclopedia=Encyclopædia Britannica |publisher=Encyclopædia Britannica, Inc. |location=Chicago |edition=Standard |year=2007 }}

As a result of the position of the eyes in its skull and the size of the cornea, the rabbit has a panoramic field of vision that encompasses nearly 360 degrees.{{Citation |last1=Peiffer |first1=Robert L. |title=Models in Ophthalmology and Vision Research |date=1994 |journal=The Biology of the Laboratory Rabbit |pages=409–433 |publisher=Elsevier |language=en |doi=10.1016/b978-0-12-469235-0.50025-7 |isbn=978-0-12-469235-0 |pmc=7149682 |last2=Pohm-Thorsen |first2=Laurie |last3=Corcoran |first3=Kelly}} However, there is a blind spot at the bridge of the nose, and because of this, rabbits cannot see what is below their mouth and rely on their lips and whiskers to determine what they are eating. Blinking occurs 2 to 4 times an hour.

=Hind limb elements=

File:Rabbit hind limb skeleton.jpg natural history collection]]

The anatomy of rabbits' hind limbs is structurally similar to that of other land mammals and contributes to their specialized form of locomotion. The bones of the hind limbs consist of long bones (the femur, tibia, fibula, and phalanges) as well as short bones (the tarsals). These bones are created through endochondral ossification during fetal development. Like most land mammals, the round head of the femur articulates with the acetabulum of the os coxae, the hip bone. The femur articulates with the tibia, but not the fibula, which is fused to the tibia. The tibia and fibula articulate with the tarsals of the pes, commonly called the foot. The hind limbs of the rabbit are longer than the front limbs. This allows them to produce their hopping form of locomotion. Longer hind limbs are more capable of producing faster speeds. Hares, which have longer legs than cottontail rabbits, are able to move considerably faster.{{Cite book|url=https://archive.org/details/practicalanatom00bensgoog|page=[https://archive.org/details/practicalanatom00bensgoog/page/n5 1]|quote=rabbit skeletal anatomy.|title=Practical anatomy of the rabbit|last=Bensley|first=Benjamin Arthur|date=1910|publisher=The University Press}} The hind feet have four long toes that allow for digitigrade movement, which are webbed to prevent them from spreading when hopping.{{Cite news|url=https://www.merckvetmanual.com/all-other-pets/rabbits/description-and-physical-characteristics-of-rabbits#v34404688|title=Description and Physical Characteristics of Rabbits – All Other Pets – Merck Veterinary Manual|work=Merck Veterinary Manual|access-date=2018-05-11}} Rabbits do not have paw pads on their feet like most other animals that use digitigrade locomotion.

==Musculature==

File:Lateral view of rabbit hind limb.jpg

Rabbits have muscled hind legs that allow for maximum force, maneuverability, and acceleration that is divided into three main parts: foot, thigh, and leg. The hind limbs of a rabbit are an exaggerated feature. They are much longer and can provide more force than the forelimbs, which are structured like brakes to take the brunt of the landing after a leap.{{Citation |last1=Khan |first1=Madiha |title=Lagomorpha Locomotion |date=2021 |encyclopedia=Encyclopedia of Animal Cognition and Behavior |pages=1–6 |editor-last=Vonk |editor-first=Jennifer |url=http://link.springer.com/10.1007/978-3-319-47829-6_1199-1 |access-date=2024-10-08 |place=Cham |publisher=Springer International Publishing |language=en |doi=10.1007/978-3-319-47829-6_1199-1 |isbn=978-3-319-47829-6 |last2=Suh |first2=Angela |last3=Lee |first3=Jenny |last4=Granatosky |first4=Michael C. |editor2-last=Shackelford |editor2-first=Todd|url-access=subscription }} The force put out by the hind limbs is contributed by both the structural anatomy of the fusion of the tibia and fibula, and by the muscular features.{{Cite book |last1=Lumpkin |first1=Susan |last2=Seidensticker |first2=John |date=2011 |title=Rabbits: the animal answer guide |publisher=Johns Hopkins University Press |isbn=978-1-4214-0126-3|location=Baltimore|oclc=794700391}}

Bone formation and removal, from a cellular standpoint, is directly correlated to hind limb muscles. Action pressure from muscles creates force that is then distributed through the skeletal structures. Rabbits that generate less force, putting less stress on bones are more prone to osteoporosis due to bone rarefaction.{{cite journal |last1=Geiser |first1=Max |last2=Trueta |first2=Joseph |title=Muscle action, bone rarefaction and bone formation |journal=The Journal of Bone and Joint Surgery.

For example, hares have a greater resistance to fatigue than cottontails. The muscles of rabbit's hind limbs can be classified into four main categories: hamstrings, quadriceps, dorsiflexors, or plantar flexors. The quadriceps muscles are in charge of force production when jumping. Complementing these muscles are the hamstrings, which aid in short bursts of action. These muscles play off of one another in the same way as the plantar flexors and dorsiflexors, contributing to the generation and actions associated with force.{{cite journal |last1=Lieber |first1=Richard L. |last2=Blevins |first2=Field T. |title=Skeletal muscle architecture of the rabbit hindlimb: Functional implications of muscle design |journal=Journal of Morphology |date=January 1989 |volume=199 |issue=1 |pages=93–101 |doi=10.1002/jmor.1051990108 |pmid=2921772 |s2cid=25344889 }}

Within the order of lagomorphs, the ears are used to detect and avoid predators.{{sfn|Varga|2013|page=62}} In the family Leporidae, the ears are typically longer than they are wide, and are in general relatively long compared to other mammals.{{Citation |last1=Bertolino |first1=Sandro |title=Eastern Cottontail Sylvilagus floridanus (J.

According to Allen's rule, endothermic animals adapted to colder climates have shorter, thicker limbs and appendages than those of similar animals adapted to warm climates. The rule was originally derived by comparing the ear lengths of Lepus species across the various climates of North America.{{cite journal |first=Joel Asaph |last=Allen |authorlink=Joel Asaph Allen |title=The influence of Physical conditions in the genesis of species |journal=Radical Review |year=1877 |volume=1 |pages=108–140 |url=http://people.wku.edu/charles.smith/biogeog/ALLE1877.htm}} Subsequent studies show that this rule remains true in the Leporidae for the ears specifically,{{Cite journal |last=Stevenson |first=Robert D. |date=1986 |title=Allen's Rule in North American Rabbits (Sylvilagus) and Hares (Lepus) Is an Exception, Not a Rule |url=https://www.jstor.org/stable/1380884 |journal=Journal of Mammalogy |volume=67 |issue=2 |pages=312–316 |doi=10.2307/1380884 |jstor=1380884 |issn=0022-2372|url-access=subscription }} in that the surface area of rabbits' and hares' ears are enlarged in warm climates;{{Cite web |url=https://fieldguide.mt.gov/speciesDetail.aspx?elcode=AMAEB03050 |work=Montana Field Guide |publisher=Montana Natural Heritage Program and Montana Fish, Wildlife and Parks |title=Black-tailed Jackrabbit - Lepus californicus |access-date=24 September 2024}} the ears are an important structure to aid thermoregulation{{Cite journal|doi=10.1016/0024-3205(71)90161-5 |title=The rabbit ear as a temperature sensor |first1=Matthew J. |last1=Kluger |first2=Richard R. |last2=Gonzalez |first3=John W. |last3=Mitchell |first4=James D. |last4=Hardy |journal=Life Sciences |volume=10 |issue= 15 |date=1 August 1971 |pages= 895–899|pmid=5566134 }} as well as in detecting predators due to the way the outer, middle, and inner ear muscles coordinate with one another.

The auricle, also known as the pinna, is a rabbit's outer ear.{{Cite journal|last=Capello|first=Vittorio|date=2006|title=Lateral Ear Canal Resection and Ablation in Pet Rabbits|url=http://www.ivis.org/proceedings/navc/2006/SAE/617.pdf?LA=1|journal=The North American Veterinary Conference|volume=20|pages=1711–1713}} The rabbit's pinnae represent a fair part of the body surface area. It is theorized that the ears aid in dispersion of heat at temperatures above {{convert|30|C|F|abbr=on }}, with rabbits in warmer climates having longer pinnae due to this. Another theory is that the ears function as shock absorbers that could aid and stabilize rabbits' vision when fleeing predators, but this has typically only been seen in hares. The rest of the outer ear has bent canals that lead to the eardrum or tympanic membrane.{{Cite journal|last=Parsons|first=Paige K.|date=2018|title=Rabbit Ears: A Structural Look: ...injury or disease, can send your rabbit into a spin|url=https://rabbit.org/journal/4-11/ear.html|journal=House Rabbit Society}}

The middle ear, separated by the outer eardrum in the back of the rabbit's skull, contains three bones: the hammer, anvil, and stirrup, collectively called ossicles, which act to decrease sound before it hits the inner ear; in general, the ossicles act as a barrier to the inner ear for sound energy.

Inner ear fluid, called endolymph, receives the sound energy. After receiving the energy. The inner ear comprises two parts: the cochlea that uses sound waves from the ossicles, and the vestibular apparatus that manages the rabbit's position in regard to movement. Within the cochlea a basilar membrane contains sensory hair structures that send nerve signals to the brain, allowing it to recognize different sound frequencies. Within the vestibular apparatus three semicircular canals help detect angular motion.

=Respiratory system=

File:Dissected Rabbit Lungs.jpg

The rabbit's nasal cavity lies dorsal to the oral cavity, and the two compartments are separated by the hard and soft palate. The nasal cavity itself is separated into a left and right side by a cartilage barrier, and it is covered in fine hairs that trap dust before it can enter the respiratory tract.{{sfn|Smith|Schenk|2019|page=73}} As the rabbit breathes, air flows in through the nostrils along the alar folds. From there, the air moves into the nasal cavity, also known as the nasopharynx, down through the trachea, through the larynx, and into the lungs.{{sfn|Smith|Schenk|2019|page=76}}{{Cite journal|last=Jekl|first=Vladimi|date=2012|title=Approach to Rabbit Respiratory Disease|url=https://www.vin.com/apputil/content/defaultadv1.aspx?id=5328323&pid=11349&print=1|journal=WSAVA/FECAVA/BSAVA World Congress|quote=As obligate nasal breathers, rabbits with upper airway disease will attempt to breathe through their mouths, which prevents feeding and drinking and could be quickly fatal.}} The larynx functions as the rabbit's voice box, which enables it to produce a wide variety of sounds.{{sfn|Smith|Schenk|2019|page=73}} The trachea is a long tube embedded with cartilaginous rings that prevent the tube from collapsing as air moves in and out of the lungs. The trachea then splits into a left and right bronchus, which meet the lungs at a structure called the hilum. From there, the bronchi split into progressively more narrow and numerous branches. The bronchi branch into bronchioles, into respiratory bronchioles, and ultimately terminate at the alveolar ducts. The branching that is typically found in rabbit lungs is a clear example of monopodial branching, in which smaller branches divide out laterally from a larger central branch.

The structure of the rabbit's nasal and oral cavities necessitates breathing through the nose. This is due to the fact that the epiglottis is fixed to the backmost portion of the soft palate. Within the oral cavity, a layer of tissue sits over the opening of the glottis, which blocks airflow from the oral cavity to the trachea.{{Cite journal|last1=Johnson-Delaney|first1=Cathy A.|last2=Orosz|first2=Susan E.|year=2011|title=Rabbit Respiratory System: Clinical Anatomy, Physiology and Disease|journal=Veterinary Clinics of North America: Exotic Animal Practice|language=en|volume=14|issue=2|pages=257–266|doi=10.1016/j.cvex.2011.03.002|pmid=21601814}} The epiglottis functions to prevent the rabbit from aspirating on its food.

=Diet and digestion=

{{Main|Cecotrope}}

Rabbits are strict herbivores and are suited to a diet high in fiber, mostly in the form of cellulose. They will typically graze grass upon waking up and emerging from a burrow, and will move on to consume vegetation and other plants throughout the waking period; rabbits have been known to eat a wide variety of plants, including tree leaves and fruits, though consumption of fruit and lower fiber foods is common for pet rabbits where natural vegetation is scarce.{{sfn|Varga|2013|pages=13-33}}

Easily digestible food is processed in the gastrointestinal tract and expelled as regular feces. To get nutrients out of hard to digest fiber, rabbits ferment fiber in the cecum (part of the gastrointestinal tract) and then expel the contents as cecotropes, which are reingested (cecotrophy or refection). The cecotropes are then absorbed in the small intestine to use the nutrients.{{Cite book|editor-first1=Katherine |editor-last1=Quesenberry |editor-first2=Connie J. |editor-last2=Orcutt |editor-first3=Christoph |editor-last3=Mans |editor-first4=James W. |editor-last4=Carpenter |first1=Susan M. |last1=Smith |title=Ferrets, Rabbits, and Rodents: Clinical Medicine and Surgery |edition=4th |date=2020 |chapter=Gastrointestinal Physiology and Nutrition of Rabbits |doi=10.1016/B978-0-323-48435-0.00013-7 |pages=162–173|isbn=978-0-323-48435-0 }} Soft cecotropes are usually consumed during periods of rest in underground burrows.{{sfn|Varga|2013|pages=13-33}}

Along with being bipartite, the female rabbit does not go through an estrus cycle, which causes mating induced ovulation.

The average female rabbit becomes sexually mature at three to eight months of age and can conceive at any time of the year for the duration of her life. Egg and sperm production can begin to decline after three years, with some species such as those in genus Oryctolagus completely stopping reproduction at 6 years of age.{{sfn|Nowak|1999|page=1730}} During mating, the male rabbit will insert his penis into the female from behind, make rapid pelvic thrusts until ejaculation, and throw himself backward off the female. Copulation lasts only 20–40 seconds.{{cite web|url=http://florida4h.org/projects/rabbits/MarketRabbits/Activity8_Mating4.html|title=Understanding the Mating Process for Breeding Rabbits|website=florida4h.org|access-date=2019-04-12}}

The rabbit gestation period is short and ranges from 27 to 30 days. A longer gestation period will generally yield a smaller litter while shorter gestation periods will give birth to a larger litter. The size of a single litter can range from 1 to 12 kits, depending on species.{{sfn|Nowak|1999|pages=1720-1732}} After birth, the only role of males is to protect the young from other rabbits, and the mother will leave the young in the nest most of the day, returning to nurse them once every 24 hours. The female can become pregnant again as early as the next day.

After mating, the doe will begin to dig a burrow or prepare a nest before giving birth. Between three days and a few hours before giving birth another series of hormonal changes will cause her to prepare the nest structure. The doe will first gather grass for a structure, and an elevation in prolactin shortly before birth will cause her fur to shed that the doe will then use to line the nest, providing insulation for the newborn kits.{{cite journal |last1=Benedek |first1=I |last2=Altbӓcker |first2=V |last3=Molnár |first3=T |date=2021 |title=Stress reactivity near birth affects nest building timing and offspring number and survival in the European rabbit (Oryctolagus cuniculus). |journal=PLOS ONE |volume=16 |issue=1 |pages=e0246258 |bibcode=2021PLoSO..1646258B |doi=10.1371/journal.pone.0246258 |pmc=7845978 |pmid=33513198 |doi-access=free}}

The mortality rates of embryos are high in rabbits and can be due to infection, trauma, poor nutrition and environmental stress. A high fertility rate is necessary to counter this. More than half of rabbit pregnancies are aborted, causing embryos to be resorbed into the mother's body;{{sfn|Nowak|1999|page=1730}} vitamin deficiencies are a major cause of abortions in domestic rabbits.{{sfn|Varga|2013|pages=34-38}}

Rabbits are native to North America, southwestern Europe, Southeast Asia, Sumatra, some islands of Japan, and parts of Africa and South America. They are not naturally found in most of Eurasia, where a number of species of hares are present. A 2003 study on domestic rabbits in China found that "(so-called) Chinese rabbits were introduced from Europe", and that "genetic diversity in Chinese rabbits was very low".

=Marking=

Both sexes of rabbits often rub their chins on objects with their scent gland located under the chin. This is the rabbit's way of marking their territory or possessions for other rabbits to recognize by depositing scent gland secretions. Rabbits who have bonded will respect each other's smell, which indicates a territorial border.{{Cite journal |last1=Hoffman |first1=Kurt L. |last2=Hernández Decasa |first2=D.

The rabbit often appears in folklore as the trickster archetype, as he uses his cunning to outwit his enemies. In Central Africa, the common hare (Kalulu) is described as a trickster figure,Brian Morris, The Power of Animals: An Ethnography, p. 177 (2000). and in Aztec mythology, a pantheon of four hundred rabbit gods known as Centzon Totochtin, led by Ometochtli or Two Rabbit, represented fertility, parties, and drunkenness.{{cite book |author=Miller, Mary |author-link=Mary Ellen Miller |url=https://archive.org/details/godssymbolsofa00mill |title=The Gods and Symbols of Ancient Mexico and the Maya: An Illustrated Dictionary of Mesoamerican Religion |author2=Karl Taube |author-link2=Karl Taube |publisher=Thames & Hudson |year=1993 |isbn=0-500-05068-6 |location=London |pages=142 |oclc=27667317 |url-access=registration}} Rabbits in the Americas varied in mythological symbolism: in Aztec mythology, they were also associated with the moon, and in Anishinaabe traditional beliefs, held by the Ojibwe and some other Native American peoples, Nanabozho, or Great Rabbit,{{Cite web |title=Nanabozho (Nanabush, Nanabosho, Wenebojo, Nanapush, Manabus) |url=http://www.native-languages.org/nanabozho.htm |url-status=live |archive-url=https://web.archive.org/web/20130328152256/http://www.native-languages.org/nanabozho.htm |archive-date=28 March 2013 |access-date=24 September 2024 |website=www.native-languages.org}} is an important deity related to the creation of the world.{{Cite book |url=http://faculty.marianopolis.edu/c.belanger/quebechistory/encyclopedia/NanabozhoIndianstoryofthecreation.htm |title=Handbook of Indians of Canada |date=1913 |editor-last=White |editor-first=James |pages=331–335 |chapter=Nanabozho and the Algonquin Story of the Creation of the World}} More broadly, a rabbit's foot may be carried as an amulet, believed to bring protection and good luck.

Rabbits have also appeared in religious symbolism. Buddhism, Christianity, and Judaism have associations with an ancient circular motif called the three rabbits (or "three hares").

In Jewish folklore, rabbits are associated with cowardice, a usage still current in contemporary Israeli spoken Hebrew. The original Hebrew word (shfanim, שפנים) refers to the hyrax, but early translations to English interpreted the word to mean "rabbit", as no hyraxes were known to northern Europe.{{Cite news |last=Gilad |first=Elon |date=13 June 2013 |title=Word of the Day Shafan: Don't Turn Yourself Into a Hyrax! |url=https://www.haaretz.com/2013-06-13/ty-article/.premium/word-of-the-day-shafan/0000017f-f44f-d47e-a37f-fd7ffb0c0000 |work=Haaretz}}

Anthropomorphized rabbits have appeared in film and literature, in Alice's Adventures in Wonderland (the White Rabbit and the March Hare characters), in Watership Down (including the film and television adaptations), in Rabbit Hill (by Robert Lawson), and in the Peter Rabbit stories (by Beatrix Potter). In the 1920s, Oswald the Lucky Rabbit was a popular cartoon character.{{cite book |last1=Susanin |first1=Timothy S. |url=https://books.google.com/books?id=OgwbBwAAQBAJ |title=Walt Before Mickey: Disney's Early Years, 1919–1928 |last2=Miller |first2=Diane Disney |date=April 7, 2011 |publisher=Univ.

On the Isle of Portland in Dorset, UK, the rabbit is said to be unlucky, and speaking the creature's name can cause upset among older island residents. This is thought to date back to early times in the local quarrying industry, where, to save space, extracted stones that were not fit for sale were set aside in what became tall, unstable walls. The local rabbits' tendency to burrow there would weaken the walls, and their collapse would result in injuries or even death. In the local culture to this day, the rabbit (when he has to be referred to) may instead be called a "long ears" or "underground mutton" so as not to risk bringing a downfall upon oneself.{{cite web |title=Wallace and Gromit spook island |url=http://news.bbc.co.uk/1/hi/england/dorset/4318710.stm |website=BBC News |access-date=25 August 2022 |date=7 October 2005}}

In other parts of Britain and in North America, "Rabbit rabbit rabbit" is one variant of an apotropaic or talismanic superstition that involves saying or repeating the word "rabbit" (or "rabbits" or "white rabbits" or some combination thereof) out loud upon waking on the first day of each month, because doing so is believed to ensure good fortune for the duration of that month.{{Cite web |last=Mayntz |first=Melissa |date=2019-04-26 |title=On the 1st Of The Month Say "Rabbit Rabbit" for Good luck! |url=https://www.farmersalmanac.com/rabbit-rabbit-35150 |access-date=2023-04-27 |website=Farmers' Almanac – Plan Your Day.

The "rabbit test" is a term first used in 1949 for the Friedman test, an early diagnostic tool for detecting a pregnancy in humans. It is a common misconception (or perhaps an urban legend) that the test-rabbit would die if the woman was pregnant. This led to the phrase "the rabbit died" becoming a euphemism for a positive pregnancy test.{{Cite journal |last=Friedman |first=Maurice |title=The Assay of Gonadotropic Extracts in the Post-Partum Rabbit11 |date=1 May 1939 |url=https://doi.org/10.1210/endo-24-5-617 |journal=Endocrinology |volume=24 |issue=5 |pages=617–625|doi=10.1210/endo-24-5-617 |url-access=subscription }}

Many modern children's stories and cartoons portray rabbits as particularly fond of eating carrots, largely due to the popularity of Bugs Bunny, whose carrot eating habit was modeled after Peter Warne, the character played by Clark Gable in the 1934 romantic comedy It Happened One Night.{{cite book|editor1-last=George|editor1-first=Amber E.|editor2-last=Schatz|editor2-first=J.L.|title=Screening the Nonhuman: Representations of Animal Others in the Media|chapter=Chapter 5: Would Bugs Bunny Have Diabetes?
