An alternative word is English puss (extended as pussy and pussycat). Attested only from the 16th century, it may have been introduced from Dutch poes or from Low German puuskatte, related to Swedish kattepus, or Norwegian pus, pusekatt. Similar forms exist in Lithuanian puižė and Irish puisín or puiscín. The etymology of this word is unknown, but it may have simply arisen from a sound used to attract a cat.[28][29]
Under the direction of Peter Weck, the first German-language production of Cats opened in September 1983 at the Theater an der Wien in Vienna, Austria. In 1988, the show transferred to the newly-renovated Ronacher Theatre where it ran for another two years before closing on its seventh anniversary in September 1990.[112][173] The Vienna production played a total of 2,040 performances to more than 2.3 million audiences.[174]

Until approximately one year of age, the kitten is undergoing a growth phase where energy requirements are up to 2.5 times higher than maintenance.[33] Pet nutritionists often suggest that a commercial cat food designed specifically for kittens should be offered beginning at 4 weeks of age.[28] Fat has a higher caloric value than carbohydrates and protein, supplying 8.5kcal/g.[34] The growing kitten requires arachidonic and linoleic acid which can be provided in omega-3 fatty acids.[23] Docosahexaenoic acid (DHA) is another vital nutrient that can be supplied through omega 3 fatty acid. Addition of DHA to the diet benefits the cognition, brain and visual development of kittens.[28]

Lloyd Webber also employs various techniques to help connect the pieces. Namely, the score relies heavily on recurring motifs as well as the use of preludes and reprises.[76] For instance, melodic fragments of "Memory" are sung by Grizabella and Jemima at several points in the show before the song is sung in full,[39] serving to characterize Grizabella and foreshadow her final number.[77][78] Similarly, Lloyd Webber introduces a fugue in the overture, and variations of this theme are then repeated throughout the musical until it is finally resolved as Grizabella ascends to the Heaviside Layer.[79]
Like almost all members of the Felidae, cats have protractable and retractable claws.[71] In their normal, relaxed position, the claws are sheathed with the skin and fur around the paw's toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows the silent stalking of prey. The claws on the fore feet are typically sharper than those on the hind feet.[72] Cats can voluntarily extend their claws on one or more paws. They may extend their claws in hunting or self-defense, climbing, kneading, or for extra traction on soft surfaces. Most cats have five claws on their front paws, and four on their rear paws.[73] The fifth front claw (the dewclaw) is proximal to the other claws. More proximally is a protrusion which appears to be a sixth "finger". This special feature of the front paws, on the inside of the wrists, is the carpal pad, also found on the paws of big cats and dogs. It has no function in normal walking, but is thought to be an antiskidding device used while jumping. Some breeds of cats are prone to polydactyly (extra toes and claws).[73] These are particularly common along the northeast coast of North America.[74]
There have been numerous notable performers in the Japanese production, including Shintarō Sonooka as Munkustrap (original 1983 cast),[170] Kanji Ishimaru as Skimbleshanks (1992),[171] Masachika Ichimura, and Mayo Kawasaki.[172] Yoshiko Hattori (ja:服部良子) holds the production's record for the longest-appearing cast member; she played Jennyanydots in the original 1983 cast and remained in the role for 20 years with a final performance tally of 4,251.[172]
The scientific name Felis catus for the domestic cat was proposed by Carl Linnaeus in the 10th edition of Systema Naturae published in 1758.[1][2] Felis catus domesticus was a scientific name proposed by Johann Christian Polycarp Erxleben in 1777.[3] Felis daemon proposed by Konstantin Alekseevich Satunin in 1904 was a black cat specimen from the Transcaucasus, later identified as a domestic cat.[38][39]
Domestic kittens are commonly sent to new homes at six to eight weeks of age, but it has been suggested that being with their mother and litter-mates from six to twelve weeks is important for a kitten's social and behavioural development.[16] Usually, breeders and foster/rescue homes will not sell or adopt out a kitten that is younger than twelve weeks. In many jurisdictions, it is illegal to give away kittens younger than eight weeks of age.[18] Kittens generally reach sexual maturity at around seven months old. A cat reaches full "adulthood" around one year of age.[19]
Many cultures have negative superstitions about cats. An example would be the belief that a black cat "crossing one's path" leads to bad luck, or that cats are witches' familiars used to augment a witch's powers and skills. The killing of cats in Medieval Ypres, Belgium, is commemorated in the innocuous present-day Kattenstoet (cat parade).[276] In medieval France, cats would be burnt alive as a form of entertainment. According to Norman Davies, the assembled people "shrieked with laughter as the animals, howling with pain, were singed, roasted, and finally carbonized".[277]
As well as being kept as pets, cats are also used in the international fur[238] and leather industries for making coats, hats, blankets, and stuffed toys;[239] and shoes, gloves, and musical instruments respectively[240] (about 24 cats are needed to make a cat-fur coat).[241] This use has been outlawed in the United States, Australia, and the European Union.[242] Cat pelts have been used for superstitious purposes as part of the practise of witchcraft,[243] and are still made into blankets in Switzerland as folk remedies believed to help rheumatism.[244] In the Western intellectual tradition, the idea of cats as everyday objects have served to illustrate problems of quantum mechanics in the Schrödinger's cat thought experiment.
A kitten is a juvenile cat. After being born, kittens are totally dependent on their mother for survival and they do not normally open their eyes until after seven to ten days. After about two weeks, kittens quickly develop and begin to explore the world outside the nest. After a further three to four weeks, they begin to eat solid food and grow adult teeth. Domestic kittens are highly social animals and usually enjoy human companionship.
Once your vet has cleared your kitten as free of disease and parasites, it’s safe to let your new kitten explore its new surroundings and other pet roommates. Handling and playing with your kitten at least once a day will help him form a strong emotional bond with you. If you have children, monitor their introduction to the new kitten to make sure it’s a positive experience for both the kitten and child.
Though it’s not something you have any control over, your kitten’s age is more than just a number. In fact, it’s crucial that you learn it. Kittens have very specific developmental needs for the first 10 weeks of their lives in terms of nourishment, warmth, socialization, and excretion. For this reason, most breeders and shelters typically wait until their kittens are of age before they’re put up for adoption. If you, by chance, find yourself in a situation where you need to care for an orphaned kitten under 10 weeks old, consult your vet for special instructions.
In ancient Egypt, cats were sacred animals, with the goddess Bast often depicted in cat form, sometimes taking on the war-like aspect of a lioness.[265]:220 Killing a cat was absolutely forbidden[4] and the Greek historian Herodotus reports that, whenever a household cat died, the entire family would mourn and shave their eyebrows.[4] Families took their dead cats to the sacred city of Bubastis,[4] where they were embalmed and buried in sacred repositories.[4] The earliest unmistakable evidence of the Greeks having domestic cats comes from two coins from Magna Graecia dating to the mid-fifth century BC showing Iokastos and Phalanthos, the legendary founders of Rhegion and Taras respectively, playing with their pet cats.[266]:57–58[267]
Domestic cats are generally smaller than wildcats in both skull and limb measurements.[58] Adult domestic cats typically weigh between 4 and 5 kg (9 and 10 lb),[48] although many breeds have a wide range of sizes, with male American Shorthairs ranging from 3 to 7 kg (7 to 20 lb).[59] Some cat breeds, such as the Maine Coon, occasionally exceed 11 kg (24 lb). Very small cats, less than 2 kg (4 lb), have been reported.[60] The world record for the largest cat is 21 kg (50 lb).[61][self-published source] The smallest adult cat ever officially recorded weighed around 1 kg (2 lb).[61] Feral cats tend to be lighter, as they have more limited access to food than house cats. The average feral adult male weighs 4 kg (9 lb), and the average adult female 3 kg (7 lb).[62] Cats average about 23–25 cm (9–10 in) in height and 46 cm (18 in) in head/body length (males being larger than females), with tails averaging 30 cm (12 in) in length.[63]
