Non-allergenic
Hypoallergenic, meaning "below average" or "slightly" allergenic, is a term meaning that something (usually cosmetics, pets, textiles, food, etc.) causes fewer allergic reactions. The term was first used in 1953 in an advertising campaign for cosmetics or perhaps as early as 1940. The term is also commonly applied to pet breeds which are claimed to produce fewer allergens than other breeds of the same species, due to some combination of their coat type, absence of fur, or absence of a gene that produces a certain protein. All breeds still produce allergens and a 2011 study failed to find a difference in allergen concentrations in homes with dogs of "hypoallergenic breeds" and other breeds. Certifications and definitions In some countries, there are allergy interest groups that provide manufacturers with a certification procedure including tests that ensure a product is unlikely to cause an allergic reaction, but such products are usually described and labeled using other but si ...

Cosmetics
Cosmetics are constituted mixtures of chemical compounds derived from either natural sources, or synthetically created ones. Cosmetics have various purposes. Those designed for personal care and skin care can be used to cleanse or protect the body or skin.

Dander
Dander is material shed from the body of humans and other animals that have fur, hair, or feathers. The term is similar to dandruff, when an excess of flakes becomes visible. Skin flakes that come off the main body of an animal are dander, while the flakes of skin called dandruff come from the scalp and are composed of epithelial skin cells. The surface layer of mammalian skin is called the stratum corneum, which is shed as part of normal skin replacement. Dander is microscopic, and can be transported through the air in house dust, where it forms the diet of the dust mites. Through the air, dander can enter the mucous membranes in the nose and lungs, causing allergies in susceptible individuals, largely through the mechanism of allergy to proteins in the bodies of the dust mites that live on dander. Dander builds up in carpets and in mattresses and pillows, so smooth surfaces predispose to an environment where levels of dander can be controlled more easily. More pet dander is slo ...

Allerca
Lifestyle Pets, formerly Allerca, was a Delaware-based company which in the mid-2000s claimed to have bred hypoallergenic cats, although it was later revealed that the company's founder had previously engaged in multiple fraudulent enterprises. According to company literature, through selective breeding the company achieved Ashera cats with significantly reduced levels of a particular protein that humans suffer allergic reactions to.

Russian Blue
The Russian Blue Cat (russian: Русская голубая кошка, Russkaya golubaya koshka), commonly referred to as just Russian Blue, is a cat breed with colors that vary from a light shimmering silver to a darker, slate grey. The short, dense coat, which stands out from the body, has been the breed's hallmark for more than a century. Origin The Russian Blue is a naturally occurring breed that may have originated in the port of Arkhangelsk in Russia.. They are also sometimes called Archangel Blues. It is believed that sailors took them from the Archangel Isles to Great Britain and Northern Europe in the 1860s. The first reference to an Archangel Cat appears in British print in 1862. The first recorded appearance of one in a show was in 1872 at The Crystal Palace in England as the Archangel Cat. However, Harrison Weir writing in 1895 reported that the early show cats under the Russian Blue name were British-bred grey tabbies, with separate grey cats arriving from Arch ...

Siberian (cat)
The Siberian is a centuries-old landrace (natural variety) of domestic cat in Russia and recently developed as a formal breed with standards promulgated the world over since the late 1980s. Siberians vary from medium to medium-large in size. The formal name of the breed is Siberian Forest Cat, but it is typically referred to as the Siberian or Siberian cat. Another formal breed name is the Moscow Semi-Longhair. The cat is an ancient breed that is now believed to be ancestral to all modern long-haired cats. The cat has similarities with the Norwegian forest cat, to which it is likely closely related. It is a natural breed from Siberia and the national cat of Russia. While it began as a landrace, it is selectively bred and pedigreed today in at least seven major cat fancier and breeder organizations. The colorpoint variant of the breed is called the Neva Masquerade by some registries, including ''Fédération Internationale Féline'' (FIFé). The Siberian is often called hypo ...

Cornish Rex
The Cornish Rex is a breed of domestic cat. The Cornish Rex has no hair except for down. Most breeds of cat have three different types of hair in their coats: the outer fur or "guard hairs", a middle layer called the " awn hair"; and the down hair or undercoat, which is very fine and about 1 cm long. Cornish Rexes only have the undercoat. They are prone to hair loss and many will develop a very thin coat or even go bald over large parts of their body. The curl in their fur is caused by a different mutation and gene than that of the Devon Rex. The breed originated in Cornwall, Great Britain. Characteristics The coat of a Cornish Rex is extremely fine and sometimes curly. Their light coat means that they are best suited for indoor living in warm and dry conditions, as they are sensitive to low temperatures. They like to stay near warm places such as computer monitors, light bulbs, laps and shoulders. The breed is sometimes referred to as the Greyhound of the cats, because ...

Devon Rex
The Devon Rex is a tall-eared, short-haired breed of cat that emerged in England during the late 1950s. They are known for their slender bodies, wavy coat, and large ears. This breed of cat is capable of learning difficult tricks but can be hard to motivate. Breed history The Devon Rex is a breed of cat with a curly, very soft short coat similar to that of the Cornish Rex. They are often thought of as one of the most hypoallergenic cats available because of their type of coat. However, they are technically not hypoallergenic. The first Devon was discovered by Beryl Cox in Buckfastleigh, Devon, UK, in 1959. The breed was initially thought to be linked with the Cornish Rex; however, test mating proved otherwise. Appearance Hair Cats have three types of hair: guard hair, awn hair, and down hair. The Devon Rex's coat is unusual because there is little guard hair. The curl in Devon Rex fur is caused by a different mutation and gene than that of the Cornish Rex and German Rex, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peterbald
The Peterbald is a cat breed of Russian origin. It was created in St Petersburg in 1994 from an experimental breeding by Olga S. Mironova. They resemble Oriental Shorthairs with a hair-losing gene. The breed was accepted for Championship class competition in 2009. Description Appearance Peterbalds resemble Oriental Shorthairs. They have a hair-losing gene and can be born bald, flocked, velour, brush, or with a straight coat. Those born with hair, excepting the straight-coats, can lose their hair over time.

Sphynx (cat)
The Sphynx cat (pronounced , ) also known as the Canadian Sphynx, is a breed of cat known for its lack of fur. Hairlessness in cats is a naturally occurring genetic mutation, and the Sphynx was developed through selective breeding of these animals, starting in the 1960s. According to breed standards, the skin should have the texture of chamois leather, as it has fine hairs, or the cat may be completely hairless. Whiskers may be present, either whole or broken, or may be totally absent. The cats have a narrow, long head and webbed feet. Their skin is the color that their fur would be, and all the usual cat markings (solid, point, van, tabby, tortie, etc.) may be found on the Sphynx cat's skin. Because they have no fur, Sphynx cats lose body heat more readily than coated cats, making them both warm to the touch and prone to seeking out warm places. Breed standards The breed standards are defined by The International Cat Association (TICA): * Wedge-shaped heads with prominent che ...

LaPerm
The LaPerm is a breed of cat. A LaPerm's fur is curly (hence the name "perm"), with the tightest curls being on the throat and on the base of the ears. LaPerms come in many colors and patterns. LaPerms generally have a very affectionate personality. Breed profile The LaPerm is a rex breed which originated in the United States and is now present in many other countries worldwide. The breed is genetically unique and not related to any other rex cat varieties, having a dominant gene causing their curly coats. They have an elegant and athletic build and are affectionate, active, and outgoing in character. They are reputed to be hypoallergenic cats, provoking a significantly lower level of an allergic response in humans than normal cats. Their most significant feature is their coat, which is made up of soft waves, curls, and ringlets, resembling a shaggy perm. History The LaPerm emerged around the early 1980s as a spontaneous mutation of cats bred for pest control. The breed found ...

Poodle Hybrids
Dog crossbreeds, sometimes called designer dogs, are dogs which have been intentionally bred from two or more recognized dog breeds. They are not dogs with no purebred ancestors, but are not otherwise recognised as breeds in their own right, and do not necessarily breed true. Early crossbreeds Several types of dog crossbreeds date from the 14th century or earlier, such as the lurcher or the longdog. Historically, crosses between dogs of different types were more well accepted at a time when modern purebred breeds (based on the eugenics principles) did not yet exist. These types of crosses were performed to aggregate qualities of two different types in the same dog or to perfect an already fixed type of dog, always for working purposes. An example to be cited is the famous case of Lord Orford's Greyhounds, which were improved by adding courage through the crossing with Old English Bulldogs, achieving the desired result after six generations. With the success of Lord Orfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
