Munchkin cat

Article Discussion

Template:Short description Template:Use mdy dates Template:Infobox Catbreed The Munchkin is a breed of cat characterized by its very short legs, which are caused by a genetic mutation. Compared to many other cat breeds, it is a relatively new breed, documented since 1940s<ref name="TICAintro" /> and officially recognized in 1991.<ref name="Fitzroy">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Munchkin is considered to be the original breed of dwarf cat.

Much controversy erupted over the breed when it was recognized by The International Cat Association (TICA) in 1997 with critics voicing concerns over potential health and mobility issues.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Many pedigree cat associations around the world have refused to recognize the Munchkin cat due to the welfare of the breed and uncertainty of the health issues,<ref name=":1" /> including the Governing Council of the Cat Fancy (GCCF).<ref name="GCCF" /> Breeding of Munchkin cats is prohibited by law in several countries due to these genetic health concerns.

The name derives from writer L. Frank Baum's diminutive inhabitants of Munchkin Country, originating in the 1900 novel, The Wonderful Wizard of Oz.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

HistoryEdit

Breed creationEdit

Short-legged cats have been documented a number of times around the world since the 1940s. A British veterinary report in 1944 noted four generations of short-legged cats which were similar to normal cats except for the length of the legs. This line disappeared during the Second World War but other short-legged cats were spotted in Russia during 1956 and the United States in the 1970s.<ref name="TICAintro">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 1983, Sandra Hochenedel, a music teacher in Rayville, Louisiana, found two pregnant cats who had been chased under a truck by a dog.<ref name=":0">Template:Cite book</ref> She kept one of the cats and named her Blackberry and half of her kittens were born short-legged. Hochenedel gave a short-legged male kitten from one of Blackberry's litters to a friend, Kay LaFrance of Monroe, Louisiana, and she named the kitten Toulouse.<ref name=":0" /> It is from Blackberry and Toulouse's litter that today's Munchkin breed is descended.<ref name=":0" />

Registry historyEdit

The Munchkin cat was first introduced to the general public in 1991 via a national network televised cat show held by The International Cat Association (TICA) in Davis, Oklahoma.<ref name="Helgren2006">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> However, the breed would not be officially recognized at that time. Critics predicted that the breed would develop back, hip and leg problems similar to those that plague some dachshunds.<ref name="NYT">Template:Cite news</ref> For many years, the Munchkin breed was not accepted in feline competitions due to the controversial breeding.<ref name=":0" /> Solveig Pflueger, a show judge, geneticist, and chairperson of TICA's Genetics Committee was a strong advocate for the official recognition of the breed. Pflueger was also a breeder of Munchkin cats herself, having been initially sent two cats from Hochenedel.<ref name="NYT" /> Amidst much controversy, the Munchkin was proposed as a new breed by foundation breeders Laurie Bobskill and Robert Bobskill of Massachusetts and accepted by TICA into its new breed development program in September 1994. Veteran show judge Katherine Crawford resigned in protest, calling the breed an affront to breeders with ethics.<ref name=":0" /><ref name="Helgren98">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Munchkin breed achieved TICA championship status in May 2003.<ref name="TICAintro" />

Currently, the only registries that fully recognize the breed are TICA, the Southern Africa Cat Council, the Australian Cat Federation, the World Cat Federation, and Catz Incorporated (New Zealand).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> There is controversy among breeders of pedigree cats as to what genetic mutations are abnormal and potentially disadvantageous to the cat.<ref name="morris">Template:Cite book</ref> Katie Lisnik, director of cat protection and policy at the Humane Society of the United States, has said: "Breeding animals for exaggerated physical characteristics, particularly when it compromises overall health, is irresponsible".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Several cat registries do not recognize the Munchkin: Fédération Internationale Féline, which refuses to recognize what they consider a breed based on a "genetic disease", achondroplasia.<ref name="FIF">Breeding and Registration Rules: 2.7.3 Genetic Diseases.

Welfare concernEdit

Breeding bansEdit

SeveralTemplate:How many countries and territories have prohibited breeding with Munchkins, including the Netherlands (2014), which prohibits breeding of all animals with genetic defects,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and Victoria (Australia).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Australian Capital Territory (a territory of Australia) government considers the Munchkin breed to be "malformed animals" and the deliberate breeding of them "unacceptable" because of the "genetic health problems associated with such breeding".<ref name="ACT">Australian Capital Territory, Code of Practice for the Welfare of Cats in the ACT</ref>

Munchkin cross-breeds like the bambino have also been subject to legal restrictions.

CharacteristicsEdit

Some sources state that the shortness of their legs does not interfere with their running and leaping abilities,<ref name="jonstroud">Template:Cite book</ref> while others state their ability to jump is limited by their condition.<ref name=":1" />

The Munchkin has similar characteristics to normal domestic cats, due to their frequent use as outcrosses. It is a small to medium-sized cat with a moderate body type and medium-plush coat. Male Munchkins typically weigh between Template:Convert and are usually larger than female Munchkins, which typically weigh between Template:Convert. The hind legs can be slightly longer than the front which creates a slight rise from the shoulder to the rump. The legs of the Munchkin may be slightly bowed, although excessive bowing is a disqualification in the show ring. Cow-hocked legs are also penalized.<ref name="TICAintro" /><ref name="Helgren2006" />

The Munchkin comes in all coat colors and patterns. It also comes in a long-haired variety, which is shown in a separate Munchkin Longhair category. The short-haired variety has a medium-plush coat while the long-haired has a semi-long silky coat.<ref name="TICAintro" /> TICA rules for outcrossing allows the use of any domestic cat that does not already belong to a recognized breed. Similarity to other breeds is grounds for disqualification. Non-standard Munchkins are not allowed to be shown.<ref name="TICAstandard">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 2014, Lilieput, a Munchkin cat from Napa, California, was named the shortest statured living cat in the world by Guinness World Records. She stands Template:Convert tall.<ref name="Yune">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

HealthEdit

The mutation that causes the shortened legs in the Munchkin is a chondrodysplasia. The Munchkin cat has an increased incidence of lordosis<ref name="orthopaedics">Template:Cite book</ref> and pectus excavatum (hollowed chest).<ref>Template:Cite book</ref>

Munchkin cats are known to be at a higher risk (than other feline breeds) for severe osteoarthritis because the shorter limbs affect their activity levels and behavior.<ref name=":1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite book</ref> Diagnosis of osteoarthritis and the assessment of its severity for a cat may require radiography.<ref name=":1" />

Many pedigree cat associations around the world have refused to recognize the Munchkin cat due to health concerns.<ref name=":1" />

GeneticsEdit

The gene causing chondrodysplasia in the Munchkin cat is caused by an autosomal dominant mutation. Only heterozygous cats are viable.<ref name="orthopaedics"/>

Punnett squares, in which the M represents the dominant Munchkin gene and the m represents the recessive normal gene, may be used to illustrate the chances of a particular mating resulting in a short-legged cat.

Derived breedsEdit

The popularity of the Munchkin<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> has led to the crossbreeding of the Munchkin with other breeds, to try to establish new, derived breeds, most of which are unrecognised by any major registry. Some named experimental crossbreeds (all of them dwarf cats) include:

  • Bambino, a mostly-hairless dwarf cat, from a cross of the Munchkin and the Sphynx breeds. Recognised by the Rare and Exotic Feline Registry (REFR).<ref>{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref> In 2019, the Netherlands Food and Consumer Product Safety Authority ordered a couple to stop breeding the Bambino due to welfare concerns.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

  • Dwelf, a cross between the Munchkin, Sphynx, and American Curl, with the defining traits of all three breeds: shortened legs, hairlessness, and curled ears. It is recognised by REFR.<ref name="REFR recog">{{#invoke:citation/CS1|citation

|CitationClass=web }}</ref>

  • Genetta, a cross between Munchkin, Bengal, and sometimes Ocicat breeds, with a spotted, striped, or marbled coat. It is recognised by REFR.<ref name="REFR recog" />
  • Kinkalow, a cross between Munchkin and American Curl, with short legs and curled ears. It is recognised by REFR.<ref name="REFR recog" />
  • Lambkin (or Nanus Rex), a cross between Munchkin and Selkirk Rex, with short legs and a curly coat. It is recognised by the REFR.<ref>{{#invoke:citation/CS1|citation

  • Skookum (or LaMerm), a cross between Munchkin and LaPerm, with the short legs of the former and curly coat of the latter. It is recognised by the REFR.<ref name="REFR recog" />
