Bengal cat
The Bengal cat is a breed of hybrid cat created from crossing of an Asian leopard cat with domestic cats, especially the spotted Egyptian Mau. It is then usually bred with a breed that demonstrates a friendlier personality, because after breeding a domesticated cat with a wildcat, its friendly personality may not manifest in the kitten. The breed's name derives from the leopard cat's taxonomic name.
Bengals have varying appearances. Their coats range from spots, rosettes, arrowhead markings, to marbling.
Etymology
The breed’s name derives from that of the Asian leopard cat, from which the Bengal cat was originally hybridized. The species epithet bengalensis is a Latin geographical adjective meaning “of Bengal”, referring to the Bengal region of South Asia.History
Early history
The earliest mention of an Asian leopard cat × domestic cross was in 1889, when Harrison Weir wrote of them in Our Cats and All About Them.Bengals as a breed
Jean Mill of California is given credit for the modern Bengal breed. She made the first known deliberate cross of an Asian leopard cat with a domestic cat. Bengals as a breed did not really begin in earnest until much later.Cat registries
In 1986, the breed was accepted as a "new breed" by The International Cat Association; Bengals gained TICA championship status in 1991. The Governing Council of the Cat Fancy accepted Bengal cats in 1997. Fédération Internationale Féline in 1999 accepted the breed into their registry. Also in 1999, Bengals were accepted into the Australian Cat Federation. The Cat Fanciers' Association accepted the Bengal in CFA's "Miscellaneous" in 2016, under the restrictions that "it must be F6 or later ".Early generations
Bengal cats from the first three generations of breeding 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. 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.Popularity
The Bengal breed was more fully developed by the 1980s. "In 1992 The International Cat Association had 125 registered Bengal Breeders." By the 2000s, Bengals had become a very popular breed. In 2019, there were nearly 2,500 Bengal breeders registered in TICA worldwide.* The 2019 number only represents the breeders who use the word "Bengal" in their cattery name.
Appearance
Markings
Colors
Bengals come in a variety of coat colors. The International Cat Association recognizes several Bengal colors: brown spotted, seal lynx point, sepia, silver, and mink spotted tabby.Spotted rosetted
The Bengal cat is the only domestic breed of cat that has rosette markings.Marble
Domestic cats have four distinct and heritable coat patterns – ticked, mackerel, blotched, and spotted – these are collectively referred to as tabby markings.Christopher Kaelin, a Stanford University geneticist, has conducted research that has been used to identify the spotted gene and the marble gene in domestic Bengal cats. Kaelin studied the color and pattern variations of feral cats in Northern California, and was able to identify the gene responsible for the marble pattern in Bengal cats.
Legal restrictions
In Australia, G5 Bengals are not restricted, but their import is complex.Bengals were regulated in the United Kingdom. In 2007, however, the Department for Environment, Food and Rural Affairs removed the previous licensing requirements.
In the United States, legal restrictions and even bans sometimes exist at the state and municipal level. In Hawaii, Bengal cats are prohibited by law. In Connecticut, it is also illegal to own any generation of Bengal cat. In Alaska, 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. In California, the code of regulations Title 14, section K, Asian leopards are not specifically listed as a restricted species. In Delaware, a permit is required to own Bengal cats. Bengals of the F1–G4 generations are also regulated in New York state, Georgia, Massachusetts, and Indiana. Various cities have imposed restrictions; in New York City, Bengals are prohibited, and there are limits on Bengal ownership in Seattle, Washington, and in Denver, Colorado. 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's Southland District, the Bengal cat requires a permit to own and is completely banned on any off-shore islands including Stewart Island.
Health
Hypertrophic cardiomyopathy (HCM)
Hypertrophic cardiomyopathy is a major concern in the Bengal cat breed. Hypertrophic cardiomyopathy is a disease in which the heart muscle becomes abnormally thick. A thick heart muscle makes it difficult for the cat's heart to pump blood.HCM is a common genetic disease in Bengal cats and there is no genetic testing available as of 2018. In the United States, 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, the North Carolina State University is attempting to identify genetic markers for HCM in the Bengal Cat.
One study published in the Journal of Internal Veterinary Medicine has claimed the prevalence of hypertrophic cardiomyopathy in Bengal cats is 16.7%.
Bengal progressive retinal atrophy (PRA-b)
Bengal cats are known to be affected by several genetic diseases, one of which is Bengal progressive 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.Erythrocyte pyruvate kinase deficiency (PK-deficiency or PK-def)
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.Ulcerative nasal dermatitis
A unique form of ulcerative dermatitis affecting the nasal planum of Bengal cats was first reported in 2004. The condition first presents between the ages of 4–12 months, beginning as a dry scale and progressing to crusts and fissures typical of hyperkeratosis. The exact cause remains unclear; it is considered hereditary and incurable, but can respond favorably to topical steroid treatments such as prednisolone and tacrolimus ointment.Life expectancy
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.Bengal blood-type
The University of [California, Davis|UC Davis] Veterinary Genetics Laboratory 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.One Bengal blood-type study that took place in the U.K. tested 100 Bengal cats. They concluded that all 100 of the Bengal cats tested had type A blood.
Shedding and grooming
Bengals are often claimed by breeders and pet adoption agencies to be a hypoallergenic breed – one less likely to cause an allergic reaction. The Bengal cat is said to produce lower than average levels of allergens, though this has not been scientifically proven as of 2020.Cat geneticist Leslie Lyons, who runs the University of Missouri's Feline and Comparative Genetics Laboratory, 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.
Bengal Longhair (Cashmere Bengal)
Some long-haired Bengals have always occurred in Bengal breeding. Many different domestic cats were used to create the Bengal breed, and it is theorized that the gene for long hair came from one of these backcrossings. UC Davis has developed a genetic test for long hair so that Bengal breeders could select Bengal cats with a recessive long-hair gene for their breeding programs.Some Bengal cats used in breeding can carry a recessive gene for long-haired. When a male and female Bengal each carry a copy of the recessive long hair gene, and those two Bengals are mated with each other, they can produce long-haired Bengals. ' In the past, long-haired offspring of Bengal matings were spayed or neutered until some breeders chose to develop the long-haired Bengal.
Long-haired Bengals are starting to gain more recognition in some cat breed registries but are not widely accepted. Since 2013, they have "preliminary" breed status in the New Zealand Cat Fancy registry, under the breed name Cashmere Bengal. Since 2017 The International Cat Association has accepted the Bengal Longhair''' in competitions.
