Minskin
The Minskin is a breed of cat derived from intentional cross-breeding between the Munchkin and Burmese cat breeds, with the addition of Sphynx and Devon Rex. It is a mostly-hairless breed of cat History Origin In 1998, Paul McSorley began developing the breed in Boston. Paul wanted a breed with the short legs of the Munchkin but a similar appearance to the colour point pattern of the Siamese; however he only wanted fur on the extremities of the cat. To achieve his desired breed he bred the Munchkin with the Sphynx to try and restrict hair to the points. He later added in Devon Rex and Burmese stock into the breed. The first cat that met the desired standard was born in July 2000. By early 2005, roughly 50 cats met the criteria. Appearance The Minskin is notable for its short stature caused by achondroplasia and the hairlessness or near hairlessness. The head of the Minskin is rounded and wide. The ears have slightly rounded tips. The eyes are large and round, set wide apart. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dwarf Cat
A dwarf cat (sometimes nicknamed a sausage cat) is a domestic cat with dwarfism due to rare genetic mutations that cause a disproportionate feline body. The mutation usually leads to significant health problems. Unlike undersized cats of normal proportions, dwarf cats suffer from the genetic mutations osteochondrodysplasia and achondroplasia (a form of osteochondrodysplasia). These genetic disorders of bone and cartilage are typically manifested as abnormal bone shape, poor growth or lack of growth, bowing of the limbs to the side – front legs are more likely to be affected, and spinal malformations. The breeding of dwarf cats is prohibited in several countries and states, due to the animal’s welfare concerns. Furthermore, except for TICA, all major cat registries neither recognize nor allow crossbreeding with dwarf cats. Characteristics The dwarf cat is recognized by its characteristically short legs, they are chondrodysplastic and have much shorter and thicker legs tha ...

Cat Breeds
Domestic cats have been diversified by humans into breeds and domestic and wild hybrids. Many such breeds recognized by various cat registries. Additionally, there are new and experimental breeds, landraces being established as standardized breeds, distinct domestic populations not being actively developed and lapsed (extinct) breeds. As of 2023, The International Cat Association (TICA) recognizes 75 standardized breeds, the Cat Fanciers' Association (CFA) recognizes 45, the Fédération Internationale Féline (FIFe) recognizes 50, the Governing Council of the Cat Fancy (GCCF) recognizes 45, and the World Cat Federation (WCF) recognizes 69. Inconsistency in a breed's classification and naming among registries means that an individual animal may be considered different breeds by different registries (though not necessarily eligible for registry in them all, depending on its exact ancestry). For example, TICA's Himalayan is considered a colorpoint variety of the Persian by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Munchkin Cat
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 and officially recognized in 1991. 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. 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, including the Governing Council of the Cat Fancy (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''. History Breed creation S ...

List Of Cat Body-type Mutations
Cats, like all living organisms, occasionally have mutations that affect their body type. Sometimes, these mutations are striking enough that humans select for and perpetuate them. However, in relatively small or isolated feral cat populations the mutations can also spread without human intervention, for example on islands. Cat breeders exploit the naturally occurring mutations by selectively breeding them in a small gene pool, resulting in the creation of new cat breeds with unusual physical characteristics. The term ''designer cat'' is often used to refer to these cat breeds. This is not always in the best interests of the cat, as many of these mutations are harmful; some are even lethal in their homozygous form. To protect the animal’s welfare it is illegal in several countries or states to breed with parent cats that bear certain of these hypertype mutations. This article gives a selection of cat body type mutant alleles and the associated mutations with a brief description. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The International Cat Association
The International Cat Association (TICA) is considered the world's largest genetic cat registry. Originally a North American organization, it now has a worldwide presence. The organization has a genetic registry for pedigreed and household pet cats and is one of the world's largest sanctioning bodies for cat shows. Activities TICA's activities include: * encouraging its members to be owners, lovers and breeders of cats who work together to promote the preservation of pedigreed cats and the health and welfare of domestic cats * maintaining a certified pedigree registry * providing cat shows which promote both pedigreed and non-pedigreed cats * promoting positive relations between breeders in the US and other countries * setting up a foundation to encourage research on feline health issues and to provide lists of resource materials on health issues to its members TICA catteries Breeding catteries register their cattery name following the TICA naming standards.

Lordosis
Lordosis is historically defined as an ''abnormal'' inward curvature of the lumbar spine. However, the terms ''lordosis'' and ''lordotic'' are also used to refer to the normal inward curvature of the lumbar and cervical vertebrae, cervical regions of the human vertebral column, spine. Similarly, kyphosis historically refers to ''abnormal'' convex curvature of the spine. The normal outward (convex) curvature in the thoracic and sacrum, sacral regions is also termed ''kyphosis'' or ''kyphotic''. The term comes . Lordosis in the human vertebral column, human spine makes it easier for humans to bring the bulk of their mass over the pelvis. This allows for a much more efficient walking Gait (human), gait than that of other primates, whose inflexible spines cause them to resort to an inefficient forward-leaning "bent-knee, bent-waist" gait. As such, lordosis in the human spine is considered one of the primary physiological adaptations of the human skeleton that allows for human gait ...

Cat Breeds Originating In The United States
The cat (''Felis catus''), also referred to as the domestic cat or house cat, is a small Domestication, domesticated carnivorous mammal. It is the only domesticated species of the family Felidae. Advances in archaeology and genetics have shown that the domestication of the cat occurred in the Near East around 7500 BC. It is commonly kept as a pet and working cat, but also ranges freely as a feral cat avoiding human contact. It is valued by humans for companionship and its ability to kill vermin. Its retractable claws are adapted to killing small prey species such as mice and rats. It has a strong, flexible body, quick reflexes, and sharp teeth, and its night vision and sense of smell are well developed. It is a social species, but a solitary hunter and a crepuscular predator. Cat intelligence is evident in their ability to adapt, learn through observation, and solve problems. Research has shown they possess strong memories, exhibit neuroplasticity, and display cognitive skil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Experimental Cat Breeds
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Pectus Excavatum
Pectus excavatum is a structural deformity of the anterior thoracic wall in which the sternum and rib cage are shaped abnormally. This produces a caved-in or sunken appearance of the chest. It can either be present at birth or develop after puberty. Pectus excavatum can impair cardiac and respiratory function and cause pain in the chest and back. People with the condition may experience severe negative psychosocial effects and avoid activities that expose the chest. Etymology Pectus excavatum is from Latin meaning ''hollowed chest''. It is sometimes referred to as sunken chest syndrome, cobbler's chest or funnel chest. Signs and symptoms The hallmark of the condition is a sunken appearance of the sternum. The most common form is a cup-shaped concavity, involving the lower end of the sternum; a broader concavity involving the upper costal cartilages is possible. The lower-most ribs may protrude ("flared ribs"). Pectus excavatum defects may be symmetric or asymmetric. People ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chondrodysplasia
An osteochondrodysplasia,Etymology: . or skeletal dysplasia, is a disorder of the development of bone and cartilage. Osteochondrodysplasias are rare diseases. About 1 in 5,000 babies are born with some type of skeletal dysplasia. Nonetheless, if taken collectively, genetic skeletal dysplasias or osteochondrodysplasias comprise a recognizable group of genetically determined disorders with generalized skeletal affection. These disorders lead to disproportionate short stature and bone abnormalities, particularly in the arms, legs, and spine. Skeletal dysplasia can result in marked functional limitation and even mortality. Osteochondrodysplasias or skeletal dysplasia subtypes can overlap in clinical aspects, therefore plain radiography is absolutely necessary to establish an accurate diagnosis. Magnetic resonance imaging can provide further diagnostic insights and guide treatment strategies especially in cases of spinal involvement. As some disorders that cause skeletal dysplasia have ...

Osteoarthritis
Osteoarthritis is a type of degenerative joint disease that results from breakdown of articular cartilage, joint cartilage and underlying bone. A form of arthritis, it is believed to be the fourth leading cause of disability in the world, affecting 1 in 7 adults in the United States alone. The most common symptoms are joint pain and Joint stiffness, stiffness. Usually the symptoms progress slowly over years. Other symptoms may include joint effusion, joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs, the knee and hip joints, and the joints of the neck and lower back. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are affected. Possible causes include previous joint injury, abnormal joint or limb development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmese Cat
The Burmese cat (, , or , or , meaning copper colour) is a cat breed, breed of domestic cat, originating in Myanmar, Burma, believed to have its roots near the Myanmar–Thailand border, Thai–Burma border and developed in the United States and Britain. Most modern Burmese are descendants of one female cat called ''Wong Mau'', which was brought from Burma to the United States in 1930 and bred with American Siamese cat, Siamese. From there, American and British breeders developed distinctly different Burmese breed standards, which is unusual among pedigreed domestic cats. Most modern cat registry, cat registries do not formally recognise the two as separate breeds, but those that do refer to the British type as the European Burmese. Originally, all Burmese cats were dark brown (genetically black), but are now available in a wide variety of colours; formal recognition of these also varies by standard. Both versions of the breed are known for their uniquely social and playf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
