TheBengal cat is abreed ofhybrid cat created from crossbreeding anAsian leopard cat todomestic cats (Prionailurus bengalensis ×Felis catus), especially the spotted tabbyEgyptian Mau. Bengals have varying appearances. Theirtabby coats range from domestic spots to hybridrosettes, arrowhead markings, and marbling. The breed is selectively bred and pedigree registered with most of the majorcat registries. The breed's name derives from the leopard cat'staxonomic name.
Due to the recent hybridisation with their wild ancestor species, the breeding, trading, and ownership of Bengal cats is legally regulated in several countries.
The breed’s name derives from that of theAsian leopard cat (Prionailurus bengalensis), from which the Bengal cat was originally hybridised.[1] The species epithetbengalensis is a Latin geographical adjective meaning “of Bengal”, referring to theBengal region ofSouth Asia.[2]
The earliest mention of anAsian leopard cat × domestic cat hybrid was in 1889, whenHarrison Weir wrote of them inOur Cats and All About Them.[3]
Jean Mill ofCalifornia, US, is given credit for the modern Bengal breed. She made the first known deliberate cross of an Asian leopard cat with a domestic cat (a black tomcat).[4] Bengals as a breed did not really begin in earnest until much later.[5]
In 1986, the breed was accepted as a "new breed" byThe International Cat Association (TICA); Bengals gained TICA championship status in 1991.[6] TheGoverning Council of the Cat Fancy (GCCF) accepted Bengal cats in 1997.[7]Fédération Internationale Féline (FIFe) in 1999 accepted the breed into their registry.[8] Also in 1999, Bengals were accepted into theAustralian Cat Federation (ACF).[9] TheCat Fanciers' Association (CFA) accepted the Bengal in CFA's "Miscellaneous" in 2016, under the restrictions that "it must be F6 or later (6 generations removed from the Asian leopard cat or non-Bengal domestic cat ancestors)".[10]
Long-haired Bengals have occurred since the early development of the breed. The long-hair trait is thought to derive from domestic cats used in the breed’s foundation, introduced throughbackcrossing. The gene responsible isrecessive, meaning that two carrier Bengals can produce long-haired offspring. Genetic testing, including a test developed by theUC Davis, US, enables breeders to identify carriers forselective breeding purposes.[11]
Historically, long-haired kittens were neutered and excluded from breeding programmes. However, some breeders later began deliberately developing the variety, often referred to as the Cashmere Bengal. Recognition of the long-haired Bengal remains limited but is increasing. Since 2013, theNew Zealand Cat Fancy (NZCF) has granted it preliminary breed status under the nameCashmere Bengal.[12] Since 2017The International Cat Association (TICA) has accepted theBengal Longhair for competition.[13]
The Bengal breed was more fully developed by the 1980s. In 1992,TICA had 125 registered Bengalbreeders.[4] By the 2000s, Bengals had become a very popular breed. In 2019, there were nearly 2,500[a] Bengal breeders registered in TICA worldwide.[14]

Bengals come in a variety of coat colours and patterns:[15][16][17][18]
Domestic cats naturally come in four distinct and heritable tabby coat patterns – ticked, mackerel, blotched, and spotted.[19] The Bengal cat is the only domestic breed of cat that hasrosette markings, due to the wild gene being inherited from the Asian leopard cat.[citation needed]
Geneticist Christopher Kaelin has conducted research atStanford University in the US that has been used to identify the spotted and the marble gene in Bengal cats. Kaelin studied the colour and pattern variations of feral cats inNorthern California, US, and was able to identify the gene responsible for the marble pattern in Bengal cats.[20]
Bengal cats from the first three generations of breeding (F1, F2, and F3) are considered "foundation" or "early-generation" Bengals. The early-generation males are frequently infertile. Therefore, female early-generation Bengals are bred to fertile domestic Bengal males of later generations.[4][21][22] Nevertheless, as the term was used incorrectly for many years, many people and breeders still refer to the cats as F2, F3, and F4, even though the term is considered incorrect.[23][clarification needed]
TheUC Davis Veterinary Genetics Laboratory in the US has studied domestic cat blood-types. They conclude that most domestic cats fall within the AB system. The common blood-types are A and B and some cats have the rare AB blood-type. There is a lack of sufficient samples from Bengals, so the genetics of the AB blood-group in Bengal cats is not well understood.[24]
One Bengal blood-type study that took place in the UK tested 100 Bengal cats. They concluded that all 100 of the Bengal cats tested had type A blood.[25]
Bengals are often claimed by breeders[26] and pet adoption agencies[27] to be ahypoallergenic breed – one less likely to causean allergic reaction. The Bengal cat is said to produce lower than average levels of allergens,[27][better source needed] though this has not been scientifically proven as of 2020.
Cat geneticistLeslie Lyons, who runs theUniversity of Missouri's Feline and Comparative Genetics Laboratory in the US, discounts such claims, observing that there is no such thing as a hypoallergenic cat. Alleged hypoallergenic breeds thus may still produce a reaction among those who have severe allergies.[28]
Hypertrophic cardiomyopathy (HCM) is a major concern in the Bengal cat breed. Hypertrophic cardiomyopathy is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). A thick heart muscle makes it difficult for the cat's heart to pump blood.[29]
HCM is a common genetic disease in Bengal cats and there is no genetic testing available as of 2018. In the US, the current practice of screening for HCM involves bringing Bengal cats to a board certified veterinary cardiologist where an echocardiogram is completed. Bengal cats that are used for breeding should be screened annually to ensure that no hypertrophic cardiomyopathy is present. As of January 2019, theNorth Carolina State University in the US is attempting to identify genetic markers for HCM in the Bengal.[30]
A study in 2013 has claimed the prevalence of hypertrophic cardiomyopathy in Bengal cats is 16.7% (95% CI = 13.2–46.5%).[31]
Bengal cats are known to be affected by several genetic diseases, one of which is Bengalprogressive retinal atrophy, also known as Bengal PRA or PRA-b. Bengal progressive retinal atrophy causes cats to slowly lose their vision and eventually become blind. The vision loss begins around 7 weeks of age and gets worse over time, with very poor eyesight by about 2 years old. Blind cats often have more trouble seeing at night and may become louder or more attached to their owners. Their pupils are usually more enlarged than normal in the same light, and they often hold their whiskers farther forward.[32]
PK deficiency is a common genetic diseases found in Bengal cats. PK deficiency is another test that is administered by the breeder. Breeding Bengal Cats should be tested before breeding to ensure two PK deficiency carriers are not mated. This is a test that a breeder must do on their own. A breeder uses a cotton swab to rub the inside of the cat's mouth and then mails the swab to the laboratory.
A unique form of ulcerativedermatitis affecting the nasal planum (rhinarium or nose leather) of Bengal cats was first reported in 2004.[33] The condition first presents between the ages of 4–12 months, beginning as a dry scale and progressing to crusts and fissures typical ofhyperkeratosis.[34] The exact cause remains unclear; it is considered hereditary and incurable, but can respond favourably to topicalsteroid treatments such asprednisolone andtacrolimus ointment.[33]
A UK study looking at veterinary records found the Bengal to have a life expectancy of 8.51 years compared to 11.74 years overall.[35]

InAustralia, G5 (fifth-generation) Bengals are not restricted, but their import is complex.[36]
Bengals were regulated in theUnited Kingdom. In 2007, however, theDepartment for Environment, Food and Rural Affairs removed the previous licensing requirements.[37]
In theUnited States, legal restrictions and even bans sometimes exist at the state and municipal level. InHawaii, Bengal cats are prohibited by law (as are all wild cat species, and all other hybrids of domestic and wild animals).[38] InConnecticut, it is also illegal to own any generation of Bengal cat.[39] InAlaska, Bengal cats must be four generations removed from the Asian leopard cat. A permit and registered pedigree that indicates the previous four generations are required.[40] InCalifornia, the code of regulations Title 14, section K, Asian leopards are not specifically listed as a restricted species. InDelaware, a permit is required to own Bengal cats.[41] Bengals of theF1–G4 generations are also regulated inNew York state,Georgia,Massachusetts, andIndiana. Various cities have imposed restrictions; inNew York City, Bengals are prohibited,[42][43] and there are limits on Bengal ownership inSeattle, Washington, and inDenver, Colorado.[44] Except where noted above, Bengal cats with a generation of G5 and beyond are considered domestic, and are generally legal in the US.
In New Zealand'sSouthland District, the Bengal cat requires a permit to own and is completely banned on any off-shore islands includingStewart Island.[45]
