Vitamin D3 is a dietary requirement for cats as they lack the ability to synthesize vitamin D3 from sunlight.[123] Cats obtain high levels of the enzyme 7-dehydrocholestrol delta 7 reductase which causes immediate conversion of vitamin D3 from sunlight to 7-dehydrocholesterol.[124] This fat soluble vitamin is required in cats for bone formation through the promotion of calcium retention, along with nerve and muscle control through absorption of calcium and phosphorus.[124]
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]
Outdoor cats are active both day and night, although they tend to be slightly more active at night.[126][127] The timing of cats' activity is quite flexible and varied, which means house cats may be more active in the morning and evening, as a response to greater human activity at these times.[128] Although they spend the majority of their time in the vicinity of their home, housecats can range many hundreds of meters from this central point, and are known to establish territories that vary considerably in size, in one study ranging from 7 to 28 hectares (17–69 acres).[127]
The "Growltiger's Last Stand" sequence has been changed multiple times over the course of the show's history. In the original London production, the "last duet" for Growltiger and Griddlebone was a setting for an unpublished Eliot poem, "The Ballad of Billy M'Caw". For the original Broadway production, the Ballad was replaced with "In Una Tepida Notte", a parody of Italian opera.[95] The mock aria was introduced so as to add more slapstick humour and its lyrics are based on the Italian translation of the "Growltiger's Last Stand" poem.[386] This new version was eventually incorporated into all other productions of Cats.[95]

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]

Perhaps the best known element of cats' hunting behavior, which is commonly misunderstood and often appalls cat owners because it looks like torture, is that cats often appear to "play" with prey by releasing it after capture. This behavior is due to an instinctive imperative to ensure that the prey is weak enough to be killed without endangering the cat.[162] This behavior is referred to in the idiom "cat-and-mouse game" or simply "cat and mouse".
The Dutch live entertainment company Stage Entertainment has been responsible for several European productions of Cats. The company produced the musical at the Coliseum Theatre in Madrid from December 2003 to January 2005, with a cast that included Víctor Ullate as Mistoffelees.[210][211] They then staged a Russian-language production at the Moscow Palace of Youth from 2005 to 2006, with a cast that included Ivan Ozhogin as Munkustrap.[212][213] A Dutch production under the same company toured the Netherlands and Belgium from 2006 to 2007,[205][214] featuring several performers in the role of Grizabella including Pia Douwes and Anita Meyer.[215][216] A Paris revival by Stage Entertainment ran at the Théâtre Mogador from October 2015 to July 2016. This production was based on the 2014 London revival and also featured a new song written especially for the French show by Lloyd Webber.[217][218]
Felines are natural carnivores and do not intentionally consume large quantities of carbohydrates. The domestic cat's liver has adapted to the lack of carbohydrates in the diet by using amino acids to produce glucose to fuel the brain and other tissues.[39] Studies have shown that carbohydrate digestion in young kittens is much less effective than that of a mature feline with a developed gastrointestinal tract.[40] Highly digestible carbohydrates can be found in commercial kitten food as a source of additional energy as well as a source of fiber to stimulate the immature gut tissue. Soluble fibre such as beet pulp is a common ingredient used as a fibrous stool hardener and has been proven to strengthen intestinal muscles and to thicken the gut mucosal layer to prevent diarrhea.[41]
One of the first things you should do with your new cat, if not the very first, is take him in for an exam. This trip is almost as important for the owner as it is the kitten, because it not only tests for health issues like birth defects, parasites, and feline leukemia, but it allows you to ask those all important questions including advice on litterbox training your kitten.
Lloyd Webber began composing the songs in late 1977 as a songwriting exercise, partly because Eliot's book had been a childhood favourite and partly to see if he could write music to predetermined lyrics. The compositions were performed privately for friends but Lloyd Webber had no further intentions for them at the time. After his song cycle Tell Me on a Sunday was televised by the BBC in early 1980, Lloyd Webber began to consider using his musicalizations of Eliot's poems in the same vein for a televised concert anthology.[8] He approached producer Cameron Mackintosh to discuss possible avenues for the songs.[9]
The cat skull is unusual among mammals in having very large eye sockets and a powerful specialized jaw.[66]:35 Within the jaw, cats have teeth adapted for killing prey and tearing meat. When it overpowers its prey, a cat delivers a lethal neck bite with its two long canine teeth, inserting them between two of the prey's vertebrae and severing its spinal cord, causing irreversible paralysis and death.[67] Compared to other felines, domestic cats have narrowly spaced canine teeth relative to the size of their jaw, which is an adaptation to their preferred prey of small rodents, which have small vertebrae.[67] The premolar and first molar together compose the carnassial pair on each side of the mouth, which efficiently shears meat into small pieces, like a pair of scissors. These are vital in feeding, since cats' small molars cannot chew food effectively, and cats are largely incapable of mastication.[66]:37 Although cats tend to have better teeth than most humans, with decay generally less likely because of a thicker protective layer of enamel, a less damaging saliva, less retention of food particles between teeth, and a diet mostly devoid of sugar, they are nonetheless subject to occasional tooth loss and infection.[68]

"Memory" is the standout hit song from Cats. By 2002, the song had been played over two million times on radio and television stations in the US.[99] It was the most requested song at piano bars and lounges in the 1980s, and was an equally popular choice at weddings, concerts and other gatherings. As of 2006, the song had been recorded around 600 times by artists such as Barbra Streisand, Barry Manilow, Judy Collins, and Johnny Mathis, in covers ranging from easy listening to techno.[334] According to Sternfeld, it is "by some estimations the most successful song ever from a musical."[318]
English-language touring companies have also toured the European region extensively. International tours in the early to late 2000s included stops in Sweden, Norway,[219] Finland,[220] Greece,[188] Portugal,[221] Germany,[222] and Italy.[223] The 2013–2014 UK tour visited cities in Belgium,[214][224] Greece, Italy,[225] Monaco, and Portugal.[153] Most recently, a UK production played in numerous European cities from 2016 to 2019, with tour stops in Switzerland, Croatia, Belgium, Poland, Bulgaria, Germany, Norway, Sweden, Finland, Denmark, Netherlands, and Luxembourg.[226] These European tours have featured several notable performers in the role of Grizabella, including Pernilla Wahlgren (Sweden; 2003),[227] Katarína Hasprová (Slovakia; 2016)[228] and Jenna Lee-James (Netherlands; 2018–2019).[229]
Among domestic cats, males are more likely to fight than females.[149] Among feral cats, the most common reason for cat fighting is competition between two males to mate with a female. In such cases, most fights are won by the heavier male.[150] Another common reason for fighting in domestic cats is the difficulty of establishing territories within a small home.[149] Female cats also fight over territory or to defend their kittens. Neutering will decrease or eliminate this behavior in many cases, suggesting that the behavior is linked to sex hormones.[151]
The original London production received mostly rave reviews, with critics hailing it as a watershed moment in British musical theatre.[295] Michael Billington of The Guardian lauded Cats as "an exhilarating piece of total theatre". Billington praised the show's "strong framework" and the ease in which the poems were integrated. He was also very impressed by Lloyd Webber's fitting compositions, Napier's environmental set, Lynne's effective and at times brilliant choreography, and Nunn's "dazzling staging" that makes use of the entire auditorium.[296] The show received similarly glowing reviews from The Sunday Times' Derek Jewell and The Stage's Peter Hepple. Jewell proclaimed it to be "among the most exhilarating and innovative musicals ever staged",[295] while Hepple declared that with Cats, "the British musical has taken a giant leap forward, surpassing in ingenuity and invention anything Broadway has sent us".[297]
The 2016 Broadway revival featured new choreography by Andy Blankenbuehler, who introduced more hip hop and cool jazz elements to the movements and dances.[55] Blankenbuehler's choreography for the ensemble numbers did not differ too much from the original by Lynne, but significant changes were made in several solo numbers, including "The Rum Tum Tugger" and "Mr. Mistoffelees".[305]
Serious damage is rare, as the fights are usually short in duration, with the loser running away with little more than a few scratches to the face and ears. However, fights for mating rights are typically more severe and injuries may include deep puncture wounds and lacerations. Normally, serious injuries from fighting are limited to infections of scratches and bites, though these can occasionally kill cats if untreated. In addition, bites are probably the main route of transmission of feline immunodeficiency virus.[153] Sexually active males are usually involved in many fights during their lives, and often have decidedly battered faces with obvious scars and cuts to their ears and nose.[154]
Cats introduced a marketing strategy that set the template for subsequent megamusicals. Early advertisements for the musical did not feature traditional pull quotes (despite many positive reviews) or any of the cast, focusing instead on branding the show itself as the star. It did this by adopting — and then aggressively promoting — a single recognisable image (the cat's-eyes logo) as the face of the show.[321] The cat's-eyes logo was the first globally marketed logo in musical theatre history,[88] and was paired with a tagline ("now and forever") to create what The Daily Telegraph called "one of musical theatre's greatest posters".[322] Such branding emblems proved equally effective for later megamusicals, as seen with the waif Cosette for Les Misérables and the Phantom's mask for The Phantom of the Opera. This advertising method had the additional effect of diminishing the importance of critical reviews, popularising the so-called "critic-proof" status of megamusicals.[321]
The musical returned to the West End in 2014 for a planned 12-week limited run at the London Palladium. Beginning on 6 December, the revival starred Nicole Scherzinger as Grizabella, and featured the original creative team, with direction from Nunn, choreography by Lynne and design by Napier.[62] Lloyd Webber was also involved and rewrote "The Rum Tum Tugger" and "Growltiger's Last Stand" for the revival.[101] The run was later extended through April 2015 and an additional 100,000 tickets were released, with Kerry Ellis replacing Scherzinger as Grizabella.[68] The musical returned once again to the London Palladium for another limited run lasting from 23 October 2015 to 2 January 2016, starring Beverley Knight as Grizabella.[102]
Cats conserve heat by reducing the flow of blood to their skin and lose heat by evaporation through their mouths. Cats have minimal ability to sweat, with glands located primarily in their paw pads,[105] and pant for heat relief only at very high temperatures[106] (but may also pant when stressed). A cat's body temperature does not vary throughout the day; this is part of cats' general lack of circadian rhythms and may reflect their tendency to be active both during the day and at night.[107]:1

Cats have excellent hearing and can detect an extremely broad range of frequencies. They can hear higher-pitched sounds than either dogs or humans, detecting frequencies from 55 Hz to 79,000 Hz, a range of 10.5 octaves, while humans and dogs both have ranges of about 9 octaves.[80][81] Cats can hear ultrasound, which is important in hunting[82] because many species of rodents make ultrasonic calls.[83] However, they do not communicate using ultrasound like rodents do. Cats' hearing is also sensitive and among the best of any mammal,[80] being most acute in the range of 500 Hz to 32 kHz.[84] This sensitivity is further enhanced by the cat's large movable outer ears (their pinnae), which both amplify sounds and help detect the direction of a noise.[82]
