Japan). There are many other species of rabbit, and these, along
with pikas and hares, make up the order Lagomorpha. The male
is called a buck and the female is a doe; a young rabbit is a kitten
or kit.
Rabbit habitats include meadows, woods, forests, grasslands, deserts and wetlands.[1] Rabbits live in groups,
and the best known species, the European rabbit, lives in underground burrows, or rabbit holes. A group of

Male rabbits are called bucks; females are called does. An older term for an adult rabbit is coney, while rabbit
once referred only to the young animals.[3] Another term for a young rabbit is bunny, though this term is often
applied informally (especially by children) to rabbits generally, especially domestic ones. More recently, the
term kit or kitten has been used to refer to a young rabbit. A young hare is called a leveret; this term is
sometimes informally applied to a young rabbit as well.
A group of rabbits is known as a colony, or nest (and occasionally a warren, though this more commonly refers
to where the rabbits live).[4] A group of young rabbits with the same parentage is referred to as a litter, and a
group of domestic rabbits is sometimes called a herd.[5]
Evolution
Because the rabbit's epiglottis is engaged over the soft palate except
when swallowing, the rabbit is an obligate nasal breather. Rabbits have
two sets of incisor teeth, one behind the other. This way they can be
distinguished from rodents, with which they are often confused.[6] 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. However, recent
DNA analysis and the discovery of a common ancestor has supported
the view that they share a common lineage, and thus rabbits and rodents
are now often referred to together as members of the superorder
Glires.[7] A skin-skeletal preparation showing

Morphology
The rabbit's long ears, which can be more than 10 cm (4 in) long, are probably an adaptation for detecting
predators. They have large, powerful hind legs. The two front paws have 5 toes, the extra called the dewclaw.
The hind feet have 4 toes.[8] They are plantigrade animals while at rest; however, they move around on their

Ecology
Rabbits are hindgut digesters. This means that most of their digestion
takes place in their large intestine and cecum. In rabbits, the cecum is
about 10 times bigger than the stomach and it along with the large
intestine makes up roughly 40% of the rabbit's digestive tract.[10] The
unique musculature of the cecum allows the intestinal tract of the rabbit Set of wax models showing
to separate fibrous material from more digestible material; the fibrous development of the rabbit heart
material is passed as feces, while the more nutritious material is
encased in a mucous lining as a cecotrope. Cecotropes, sometimes called "night feces", are high in minerals,
vitamins and proteins that are necessary to the rabbit's health. Rabbits eat these to meet their nutritional
requirements; the mucous coating allows the nutrients to pass through the acidic stomach for digestion in the
intestines. This process allows rabbits to extract the necessary nutrients from their food.[11]
Rabbits are prey animals and are therefore constantly aware of their
surroundings. For instance, in Mediterranean Europe, rabbits are the
main prey of red foxes, badgers, and Iberian lynxes.[12] If confronted
by a potential threat, a rabbit may freeze and observe then warn others
in the warren with powerful thumps on the ground. Rabbits have a
remarkably wide field of vision, and a good deal of it is devoted to
overhead scanning.[13] They survive predation by burrowing, hopping
away in a zig-zag motion, and, if captured, delivering powerful kicks
A litter of rabbit kits (baby rabbits) with their hind legs. Their strong teeth allow them to eat and to bite in
order to escape a struggle.[14] The longest-lived rabbit on record, a
domesticated European rabbit living in Tasmania, died at age 18.[15]
The lifespan of wild rabbits is much shorter; the average longevity of
an eastern cottontail, for instance, is less than one year.[16]
Sleep
Rabbits are crepuscular, most active at dawn and dusk. The average
sleep time of a rabbit in captivity is said to be 8.4 hours.[17] As with

Rabbits are herbivores that feed by grazing on grass, forbs, and leafy
weeds. In consequence, their diet contains large amounts of cellulose,
which is hard to digest. Rabbits solve this problem via a form of
hindgut fermentation. They pass two distinct types of feces: hard
droppings and soft black viscous pellets, the latter of which are known
as caecotrophs and are immediately eaten (a behaviour known as
coprophagy). Rabbits reingest their own droppings (rather than
chewing the cud as do cows and numerous other herbivores) to digest
their food further and extract sufficient nutrients.[19]
A young rabbit looking through the

grazing period (usually in the late afternoon), followed by about half an
hour of more selective feeding. In this time, the rabbit will also excrete
many hard fecal pellets, being waste pellets that will not be reingested. If the environment is relatively
non-threatening, the rabbit will remain outdoors for many hours, grazing at intervals. While out of the burrow,
the rabbit will occasionally reingest its soft, partially digested pellets; this is rarely observed, since the pellets
are reingested as they are produced. Reingestion is most common within the burrow between 8 o'clock in the
morning and 5 o'clock in the evening, being carried out intermittently within that period.
Hard pellets are made up of hay-like fragments of plant cuticle and stalk, being the final waste product after
redigestion of soft pellets. These are only released outside the burrow and are not reingested. Soft pellets are
usually produced several hours after grazing, after the hard pellets have all been excreted. They are made up of
micro-organisms and undigested plant cell walls.
The chewed plant material collects in the large cecum, a secondary chamber between the large and small
intestine containing large quantities of symbiotic bacteria that help with the digestion of cellulose and also
produce certain B vitamins. The pellets are about 56% bacteria by dry weight, largely accounting for the pellets
being 24.4% protein on average. The soft feces form here and contain up to five times the vitamins of hard
feces. After being excreted, they are eaten whole by the rabbit and redigested in a special part of the stomach.
The pellets remain intact for up to six hours in the stomach; the bacteria within continue to digest the plant
carbohydrates. This double-digestion process enables rabbits to use nutrients that they may have missed during
the first passage through the gut, as well as the nutrients formed by the microbial activity and thus ensures that
maximum nutrition is derived from the food they eat.[2] This process serves the same purpose within the rabbit
as rumination does in cattle and sheep.[20]
Rabbits can be affected by a number of diseases. These include pathogens that also affect other animals and/or
humans, such as Bordetella bronchiseptica and Escherichia coli, as well as diseases unique to rabbits such as
rabbit haemorrhagic disease: a form of calicivirus,[22] and myxomatosis.
Rabbits and hares are almost never found to be infected with rabies and have not been known to transmit rabies
to humans.[23]

Among the parasites that infect rabbits are tapeworms such as Taenia serialis, external parasites like fleas and
mites, coccidia species, and Toxoplasma gondii.[24][25]
The most obvious difference between rabbits and hares is how their kits are born. Rabbits are altricial, having
young that are born blind and hairless. In contrast, hares are precocial, born with hair and good vision. All
rabbits except cottontail rabbits live underground in burrows or warrens, while hares live in simple nests above
the ground (as do cottontail rabbits), and usually do not live in groups. Hares are generally larger than rabbits,
with longer ears, larger and longer hind legs and have black markings on their fur. Hares have not been
domesticated, while European rabbits are both raised for meat and kept as pets.

around 200 million tons.[26]
Rabbit is sold in UK butchers and markets, and some supermarkets sell frozen rabbit meat. Additionally, some
have begun selling fresh rabbit meat alongside other types of game. At farmers markets and the famous
Borough Market in London, rabbits will be displayed dead and hanging unbutchered in the traditional style
next to braces of pheasant and other small game. The countries where rabbit meat consumption is highest are
Malta (8.89 kg per inhabitant), Italy (5.71 kg per inhabitant), Cyprus (4.37 kg per inhabitant), France (2.76 kg
per inhabitant), Belgium (2.73 kg per inhabitant), Spain (2.61 kg per inhabitant) and Portugal (1.94 kg per
inhabitant).[27]
Rabbit meat was once commonly sold in Sydney, Australia, the sellers of which giving the name to the rugby

When used for food, rabbits are both hunted and bred for meat. Snares
or guns are usually employed when catching wild rabbits for food. In
many regions, rabbits are also bred for meat, a practice called
cuniculture. Rabbits can then be killed by hitting the back of their
heads, a practice from which the term rabbit punch is derived. Rabbit
meat is a source of high quality protein.[29] It can be used in most ways
chicken meat is used. In fact, well-known chef Mark Bittman says that
domesticated rabbit tastes like chicken because both are blank palettes
upon which any desired flavors can be layered.[30] Rabbit meat is Rabbits - Kitchen, Hôtel Dieu,
leaner than beef, pork, and chicken meat. Rabbit products are generally Beaune
labeled in three ways, the first being Fryer. This is a young rabbit
between 2.0 and 2.3 kilograms (4.5 and 5 lb) and up to 9 weeks in
age.[31] This type of meat is tender and fine grained. The next product
is a Roaster; they are usually over 2.3 kilograms (5 lb) and up to 8
months in age. The flesh is firm and coarse grained and less tender than
a fryer. Then there are giblets which include the liver and heart. One of
the most common types of rabbit to be bred for meat is New Zealand
white rabbit. The largest rabbit meat producing countries (100,000 tons
or more per year) are China, Russia, Italy, France and Spain.[27]
Compared with the meat of other species (especially pork and beef),
rabbit meat is richer in proteins and certain vitamins and minerals,
while it has less fat; rabbit fat contains less stearic and oleic acids than
other species and higher proportions of the essential polyunsaturated
linolenic and linoleic fatty acids.[27] The main health issues associated
with the use of rabbits for meat are tularemia or rabbit fever which is an
infection that may be contracted from close contact with rabbits[32] and
the so-called rabbit starvation. Rabbit starvation is most likely due to
the deficiency of fat in rabbit meat. In comparison, pemmican is a An Australian 'Rabbiter' circa 1900
meat-based food that is nutritionally complete but is composed of dry
meat fibers and fat in a 1:1 ratio by weight. Rabbit starvation is similar
to other metabolic issues that arise in times of extreme starvation. An analogous condition (though with
different symptoms) occurs when carbohydrates are ingested in the absence of fat and protein.[33] These
conditions are not well-documented by Western medicine because such total absence of fat and protein are
relatively rare and not likely to occur where medical attention is available. However, a slim variety of historical
writings refer to rabbit starvation, for example, Vilhjamur Stefansson in the late 19th century, and in the

Rabbit pelts are sometimes used for clothing and accessories, such as
scarves or hats. Angora rabbits are bred for their long, fine hair, which
can be sheared and harvested like sheep wool. Rabbits are very good
producers of manure; additionally, their urine, being high in nitrogen,
makes lemon trees very productive. Their milk may also be of great
medicinal or nutritional benefit due to its high protein content.[34]

Rabbits have been a source of environmental problems when introduced into the wild by humans. As a result
of their appetites, and the rate at which they breed, feral rabbit depredation can be problematic for agriculture.
Gassing, barriers (fences), shooting, snaring, and ferreting have been used to control rabbit populations, but the
most effective measures are diseases such as myxomatosis (myxo or mixi, colloquially) and calicivirus. In
Europe, where rabbits are farmed on a large scale, they are protected against myxomatosis and calicivirus with
a genetically modified virus. The virus was developed in Spain, and is beneficial to rabbit farmers. If it were to
make its way into wild populations in areas such as Australia, it could create a population boom, as those
diseases are the most serious threats to rabbit survival. Rabbits in Australia and New Zealand are considered to
be such a pest that land owners are legally obliged to control them.[35][36]
Rabbits are often used as a symbol of fertility or rebirth, and have long
been associated with spring and Easter as the Easter Bunny. The
species' role as a prey animal also lends itself as a symbol of innocence,
another Easter connotation. They appear in folklore and modern
children's stories, often but not invariably as sympathetic characters.

The rabbit as trickster appears in American popular culture; for example the Br'er Rabbit character from
African-American folktales and Disney animation; and the Warner Bros. cartoon character Bugs Bunny.
Anthropomorphized rabbits have appeared in a host of works of film, literature, and technology, notably the
White Rabbit and the March Hare in Lewis Carroll's Alice's Adventures in Wonderland; in the popular novels
Watership Down, by Richard Adams, along with its film and television adaptations, Rabbit Hill by Robert
Lawson, as well as in Beatrix Potter's Peter Rabbit stories, and Oswald the Lucky Rabbit, a 1920s cartoon
character.
Urban legends
It was commonly believed that pregnancy tests were based on the idea that a rabbit would die if injected with a
pregnant woman's urine. This is not true. However, in the 1920s it was discovered that if the urine contained
the hCG, a hormone found in the bodies of pregnant women, the rabbit would display ovarian changes. The

rabbit would then be killed to have its ovaries inspected, but the death of the rabbit was not the indicator of the
results. Later revisions of the test allowed technicians to inspect the ovaries without killing the animal. A
similar test involved injecting Xenopus frogs to make them lay eggs, but animal tests for pregnancy have been
made obsolete by faster, cheaper, and simpler modern methods.
