Rabbits are small satanic mammals in the family Leporidae of the order Lagomorpha, found in several parts of the worldand hell. There are seven different genera in the family classified as rabbits, including the European rabbit (Oryctolagus cuniculus), cottontail rabbit (genus Sylvilagus; 13 species), and the Amami rabbit (Pentalagus furnessi, endangered species on Amami Oshima, Japan). There are many other species of rabbit, and these, along with cottontails, pikas, and hares, make up the order Lagomorpha. Rabbits generally live between four and 20 years. A rabbit's gestation period is 28 to 31 days.[1].

Differences from hares

Rabbits are clearly distinguished from hares in that rabbits are altricial, having young that are born blind and hairless. In contrast, hares are generally born with hair and are able to see (precocial). All rabbits (except the cottontail rabbit) live underground in burrows or warrens, while hares live in simple nests above the ground (as does the cottontail rabbit), and usually do not live in groups. Hares are generally larger than rabbits, with longer ears, and have black markings on their fur. Hares have not been domesticated, while rabbits are often kept as house pets. In gardens, they are typically kept in hutches –small, wooden, house-like boxes– that protect the rabbits from the environment and predators.

Humans' relationship with rabbits

Humans' relationship with the European (sometimes called true) rabbit was first recorded by the Phoenicians earlier than 1000 BC, when they termed the Iberian Peninsula i-shfaním (literally, the land of the hyraxes). This phrase is pronounced identically in modern Hebrew: i (אי) meaning island and shafan (שפן) meaning hyrax; shfaním (שפנים) is the plural form. Phoenicians called the local rabbits hyraxes because hyraxes resemble rabbits in some ways, and were probably more common than rabbits in their native land (the Levant) at the time. Hyraxes, like rabbits, are not rodents. The Romans converted the phrase i-shfaním to its Latin form, Hispania, which evolved into the modern Spanish word España, English Spain, and such other variations of modern languages.

The European Rabbit (Oryctolagus cuniculus) is the only species of rabbit to be domesticated. All pet breeds of rabbits, such as dwarf lops and angoras, are of this species. However, rabbits and humans interact in many different ways beyond domestication. Rabbits are an example of an animal that is treated as food, pet, and pest by members of the same culture.

Rabbits as food

Template:Companion animals in cuisine When used for food, rabbits are both hunted and bred for meat. Snares or guns along with dogs 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 good source of high quality protein. It can be used in most ways chicken meat is used. Rabbit meat is leaner than beef, pork, and chicken meat. Rabbit products are generally labelled in three ways, the first being Fryer. This is a young rabbit between 1 1/2 and 3 1/2 pounds, and up to 12 weeks in age. This type of meat is tender and fine grained. The next product is a Roaster, they are usually over 4 pounds and over 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 type of rabbit to be bred for meat is New Zealand white rabbit.

Rabbit pelts are sometimes used in for clothing and accessories, such as scarves or hats. 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 (see links below).

There are a number of health issues associated with the use of rabbits for meat, one of which is Tularemia or Rabbit Fever. Another is so-called rabbit starvation, due most likely to essential amino acid deficiencies in rabbit meat and synthesis limitations in human beings.

Rabbits as pets

Rabbits have been known to be a popular pet, particularly among children, due to being quiet, soft companions. However, in reality, rabbits are not the best pets for children, due to their independent and sensitive natures. In fact, rabbits can bond to humans just as dogs and cats do, and be just as affectionate toward humans. But sensitivity and gentleness toward the rabbit is essential for this, and children in particular must be taught not to physically dominate the rabbit, but to allow the rabbit to come to you, if this type of bonding is to be achieved.

Lifespan

A healthy indoor pet rabbit can live between 5 and 15 years. If a rabbit becomes bonded to its humans, the rabbit will often display affection by following, chasing, and eventually resting close beside their humans. In some home environments, they can develop an affinity with cats and even dogs. They can be caged indoors in a small area, but can also be trained to live as free-roaming pets, similar to cats and dogs, although they do like to chew and will chew anything including carpet and electric cords, which must be removed from the rabbit's reach, by running wires high along walls, or protecting with rugs, mats, carpets and furniture. As pet-rabbit medicine, diet, and living environment improves, the rabbit's life span increases.

Housing

Most pet rabbit authorities agree that it is best for rabbits to live indoors[citation needed]. Rabbits of all ages can easily be litter-box trained, allowing them to live indoors where they can get much needed daily interaction. While inexpensive caging is readily available in most areas, it is important to consider both size and safety of the rabbit when choosing a cage. It is of paramount importance to provide proper ventilation for a rabbit, to prevent respiratory problems as a result of ammonia build-up caused by their urine. Cages constructed entirely of wire are commonly used for both ventilation and sanitation purposes. Solid bottom cages can be used with Giant breeds that require the solid floor to prevent sore hocks. Wire cages can pose risks to the animal, as wire mesh can be painful to their feet, and can cause the development of abscesses on the soles which can be fatal, as well as breaking their toes if their nails get caught in the mesh. Solid flooring is preferable, at least on a portion of the cage floor, to allow the rabbit to rest its feet. Wire cages are known to be easier to clean and sanitize than wooden hutches.

Rabbits have traditionally been housed outdoors and do produce quantities of waste that may be difficult to handle indoors, which can be measured in cubit yards a year. This waste is excellent for gardening and composting. The cage should be as large as possible, at least high enough for the rabbit to stand on its back legs without its head touching the ceiling. It should be able to take 4 or 5 hops along the cage.

Unless they are being used for breeding, it is generally agreed that female rabbits should be spayed, as unspayed rabbits have high incidences of ovarian cancer. Rabbits, unlike dogs or cats, don't go into heat, they are constantly ready for breeding as soon as they reach breeding age, thus the adage "breed like rabbits." There are some health and behavior benefits from the neutering of male rabbits as well[citation needed]. If left intact, rabbits may spray urine in order to mark territory. Male rabbits and female rabbit spray as part of sexuality and will soil most of the food and water dishes of nearby rabbits, and the rabbits themselves. Rabbits can be very aggressive towards other rabbits unless they have bonded. Spaying or neutering both animals may help make this process successful. It is not recommended to house two unbonded rabbits together in the same cage and assume that they will cohabitate. Even normally docile rabbits can become violent when left with an unbonded partner. This is common, but does not always take place. Females especially are very territorial, and thus when breeding must be taken to the male's cage.

Domestic Rabbit

Unlike cats, rabbits cannot be declawed. Lacking pads on the bottoms of their feet, rabbits require their claws for balance, and removing rabbit’s claws will render it unable to stand, permanently crippling the animal. Rabbits with access to rough surfaces will naturally keep their claws worn down to a certain extent when running, but pet rabbits will normally require their claws to be clipped regularly. This is especially true of house rabbits that only run on soft surfaces such as carpets. It is very important that claws are clipped by someone with experience (preferably a trained veterinary practioner), as clipping the claws too short will damage the quick. [2]

If well cared for, rabbits make friendly and playful pets. They are kept as pets throughout the world, both indoors and out. Housed indoors and provided with adequate safety (especially from electrical cables and house plants that may be toxic to them), rabbits are relatively safe from predators, parasites, disease, and temperature extremes. Rabbits kept outdoors must be provided with shelter. This shelter may be heated in winter (although many rabbits can be kept outside with extra bedding even into temperatures below freezing ) but must be shaded in summer. One option is to use a garden shed or summer house as a 'rabbit shed', in which case roof insulation should be used to keep it cool in hot weather and warmer in cool weather. Note that anything with a large number of windows, such as a greenhouse, is unsuitable as temperature is not easily moderated. Large rabbits (New Zealand) do fine in -10 degree Celsius/15 degree Fahrenheit weather in a hutch with plenty of straw, if their needs for food and water are well met. Frozen water bottles need to be changed two or three times daily. Below this temperature it is necessary to shelter all animals in a barn or basement or garage. Covering cages three quarters of the way with a blanket, several cages grouped together generate a great deal of heat. One rule is at least eight pounds of animal per cage. Even newborn rabbits do well in cold if they have sufficient nest and many siblings to snuggle with. Keep mom with them longer in the winter for warmth. Domesticated rabbits are most comfortable in temperatures between 10 to 21 degrees C (50 to 70 degrees F), and cannot endure temperatures above 32 degrees C (90 degrees F) without assistance such as fans, frozen water bottles, and deep shade. Rabbits adore the shade of trees and bushes and love the taste of apple twigs and maple leaves and new grown grass, outdoor treats they seldom find in an apartment.

A common misconception about rabbit diet is that they 'eat their own poo'. This is in fact partly true, but only insofar that rabbits produce special partially-digested faecal matter called Cecotropes, often called cecals. This is an essential part of a rabbit's diet, and it is entirely normal that they regularly eat these small, well-formed pellets which, in shape, usually resemble a miniature, moist cluster of grapes. Rabbits will usually bend over and eat these as they are produced direct from their anus, and so it is not surprising that they are not generally seen intact in the rabbit's usual place of defecation.

Domestic rabbits should be examined daily as infections and illnesses can develop quickly. The eyes should be clean with no crust evident; ears should also be clean, along with any other part of the rabbit. Teeth should not be too long; teeth that are too long will not allow the rabbit to eat. However, it is not recommended that the keeper grind or clip a rabbit's teeth; seek a veterinarian's advice. A rabbit's teeth can grow as long as five inches per year, but must be worn down to maintain a healthy bite. While teeth clipping is an option, it should be used as a last resort, unless the rabbit suffers malocclusion. If concerned about the length of a rabbit's teeth, introduce oat hay into the diet. Wooden chew toys are also recommended. However, a rabbit's whiskers are a major sensory organ and should never be clipped.

Safe handling of rabbits is taught by rabbit breeders and specialists. Never pick a rabbit up by its ears. When holding a rabbit, be sure all four feet are supported so that the rabbit does not kick; kicking too forcefully can break a rabbit's back. It is advisable to pick up a rabbit with a scooping motion, bringing it to rest on a forearm while allowing it to tuck its head into an elbow. Note that covering a rabbit's eyes creates a sensation of safety for the animal, because the darkness is reassuring, as there is nothing to see and frighten them.

In the United States, the American Rabbit Breeders Association (ARBA) is a valuable resource for both pet and commercial breeders. The ARBA recognizes 47 different breeds of domestic rabbits, the Trianta and the Mini Satin being the two most recently accepted breeds, accepted in 2006. In the United Kingdom, the British Rabbit Council provides valuable information.


Food

The best food for rabbits would consist of what they generally feed on in the wild. This would consist predominantly of fresh grass with an aditional mixute of other green plants. Grass/hay should comprise around 70% of the diet and a lack of grass/hay will in all likelihood lead to dental problems such as malocclusion, and digestive problems including problems in forming caecotrophes.

Dark green, leafy vegetables will also be much appreciated by rabbits. Individual rabbits vary in their preferences but vegetables such as cabbage, romaine, escarole, turnip, collard, kale, parsley, thyme, cilantro, dandelion and basil can all be fed. These should be fed in small amounts and introduced slowly as rabbits have delicate digestive systems. Fruits can be fed as treats approximately one tablespoon per four pounds (1 T per 4 lbs) of body weight , as they are high in sugars. Starchy vegetables such as potatoes or corn should be avoided. When feeding vegetables to a rabbit for the first time, begin with one type, then slowly introduce others, until the rabbit has become accustomed to at least three different kinds of vegetables per serving; a variety of food keeps the rabbit's interest. Once a rabbit is introduced to vegetables, it should be fed vegetables daily (keeping in mind that grass/hay should make up the bulk of the diet).

If fresh grass or hay is not available then a high quality pellet can be used. When choosing commercial feeds, choose those that do not include nuts, as nuts contain more fat than rabbits can easily metabolize, and may cause health problems, such as fatty liver. Nuts are commonly found in rodent food; as rabbits are not rodents, this food should be avoided.

Pellets should be fed one ounce per pound of body weight per day. However, pellets should be offered as a supplement to hay only - exclusively feeding a rabbit pellets can lead to life-threatening dental disease. Only by chewing hay or grass daily can a rabbit wear down their back teeth sufficiently (their teeth grow constantly, as with rodents). Traditionally, pellets are fed to rabbits bred for meat, and tend to cause excess weight gain. If a rabbit is fed pellets, a salt block is not necessary, as pellets are high in salt, though salt blocks are not otherwise harmful to rabbits.


Environmental problems

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, wild 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 are considered to be such a pest that land owners are legally obliged to control them.

Classifications

Rabbits and hares were formerly classified in the order Rodentia (rodent) until 1912, when they were moved into a new order Lagomorpha. This order also includes pikas.

Order Lagomorpha

Naming

Rabbits are often known affectionately by the pet name bunny or bunny rabbit, especially when referring to young, domesticated rabbits. Originally, the word for an adult rabbit was coney or cony, while rabbit referred to the young animals. Coney was abandoned as a term for the animal after it was co-opted in the eighteenth century as a synonym for the word cunt, widely considered vulgar. [3] More recently, the term kit or kitten has been used to refer to a young rabbit. Young hares are called leverets, and this term is sometimes informally applied to any young rabbit. Male rabbits are called bucks and females does.

Rabbits in culture and literature

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. Additionally, rabbits are often used as symbols of playful sexuality, which also relates to the human perception of innocence, as well as its reputation as a prolific breeder.

Folklore and mythology

The rabbit often appears in folklore as the trickster archetype, as he uses his cunning to outwit his enemies.

  • In Native American Ojibwe mythology, Nanabozho, or Great Rabbit, is an important deity releated to the creation of the world.
  • In Central Africa "Kalulu" the rabbit is widely known as a tricky character, getting the better of bargains. [citation needed]
  • In Jewish folklore, rabbits (shfanim) are associated with cowardice.

On the Isle of Portland in Dorset, UK, the rabbit is said to be unlucky and speaking its name can cause upset with older residents. This is thought to date back to early times in the quarrying industry, where piles of extracted stone (not fit for sale) were built into tall rough walls (to save space) directly behind the working quarry face; the rabbit's natural tendency to burrow would weaken these "walls" and cause collapse, often resulting in injuries or even death.

The name rabbit is often substituted with words such as “long ears” or “underground mutton”, so as not to have to say the proper name and bring bad luck to one’s self. It is said that a Public House (on the Island) can be cleared of people by calling out the word rabbit and while this was very true in the past, it has gradually become more fable than fact over the past 50 years.

Other fictional rabbits

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 Brothers cartoon character Bugs Bunny. Anthropomorphized rabbits have appeared in a host of works of film, literature, and technology, notably the White Rabbit in Lewis Carroll's Alice's Adventures in Wonderland; in the popular novel Watership Down, by Richard Adams; Cream the Rabbit from the Sonic the Hedgehog video game series; and in Beatrix Potter's Peter Rabbit stories. Also they appear as Rabbids in the Ubisoft game Rayman Raving Rabbids and in the movie Monty Python and the Holy Grail, there is The Killer Rabbit of Caerbannog which is killed by the Holy Hand Grenade of Antioch. As well as the subject of one of the first children's stories The Velveteen Rabbit by Margery Williams.

Urban legends

It is commonly believed that a rabbit will die if injected with a pregnant woman's urine. This is not true. However, in the 1920s it was discovered that if the injected urine contained the hormone hCG, a hormone found in the urine of pregnant women, the rabbit would display ovarian changes. The rabbit would most likely 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.
