Despite mixed reviews when Cats opened in New York in 1982, critics agreed that it was innovative and visually spectacular in ways that Broadway had never seen before.[304] The musical became a cultural phenomenon and has had a profound influence on the medium.[312] Cats established musical theatre as a global commodity,[313][314] marking the beginning of a new era in the industry that is characterised by huge global stakes for potentially even huger global profits.[313] It led the shift in the Broadway market towards big-budget blockbusters and shows that appeal to families and tourists,[88][315] which in turn left smaller productions struggling to compete.[314] Cats also ushered in a "golden age of British musicals" which saw West End exports dominate the industry for nearly two decades.[316][317] Musical theatre historian Vagelis Siropoulos asserted that its "seminal Broadway opening" was "comparable only to Rodgers and Hammerstein's Oklahoma! thirty nine years ago."[313]

Cats can synthesize niacin, but their breakdown exceeds the rate that it can be synthesized and thus, have a higher need for it, which can be fulfilled through an animal-based diet.[24] Pyridoxine (vitamin B6) is required in increased amounts seeing as it is needed to produce amino acids.[24] To continue, vitamin B12 is an AAFCO-recommended vitamin essential in the metabolism of carbohydrates and protein and maintains a healthy nervous system, healthy mucous membranes, healthy muscle and heart function and in general, promotes normal growth and development.[42] Choline is also a AAFCO recommended ingredient for kittens, which is important for neurotransmission in the brain and as a component of membrane phospholipids.[24] Biotin is another AAFCO-recommended vitamin to support thyroid and adrenal glands and the reproductive and nervous systems.[24] Kittens also require riboflavin (vitamin B2) for heart health, pantothenic acid (vitamin B5), and folacin.[42]
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]
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]

After Hamburg, the German production transferred to Stuttgart where it played from 2001 to 2002.[182][183] Stage Entertainment took over the production mid-2002 and moved the show to Berlin (2002–2004)[184][185] and later Düsseldorf (2004–2005),[186] before touring other cities until 2006.[187][188] Mehr-Entertainment launched a separate tour of Cats that ran from December 2010 to June 2013, performing in a travelling purpose-built tent theatre.[180] Besides Germany, this company also made stops in cities in Luxembourg, Switzerland and Austria.[189]
The sex of kittens is usually easy to determine at birth. By six to eight weeks they are harder to sex because of the growth of fur in the genital region. The male's urethral opening is round, whereas the female's urethral opening is a slit. Another marked difference is the distance between anus and urethral opening, which is greater in males than in females.[15]
To keep up with your kitten’s appetite, you’ll want to establish a daily feeding routine. The best way to ensure that you’re not under or over-feeding your kitten is to consult with you veterinarian about how much and how often to feed. At 3 to 6 moths of age, most vets recommend feeding your kitten three times a day. Once he’s reached six months, you can scale it back to twice a day. Keep stocking your pantry with kitten food until your baby reaches adulthood, 9 to12 months old. In addition, don’t forget to keep his water bowl fresh and filled at all times. But hold the milk. Contrary to popular belief, milk is not nutritionally sufficient for kittens and can give them diarrhea.

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]
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]
Cats premiered in the West End at the New London Theatre on 11 May 1981. The musical was produced by Mackintosh and Lloyd Webber's Really Useful Group, with direction by Nunn, choreography by Lynne (who also served as the associate director), set and costume design by Napier, lighting design by David Hersey, sound design by Abe Jacob and music direction by Harry Rabinowitz.[98] It played a total of 8,949 performances before closing on its 21st anniversary, 11 May 2002. The final performance was broadcast live on a large outdoor screen in Covent Garden for fans who could not acquire a ticket.[99] Cats held the record as London's longest-running musical from 1989, when it surpassed Jesus Christ Superstar,[100] until 8 October 2006, when it was surpassed by Les Misérables.

Before you bring your kitten home, it’s best to designate a quiet area where the kitten can feel comfortable and safe. In this base camp, you’ll need to put a few essentials like food and water dishes, a litterbox (preferably one with low sides), and some comfortable bedding. Tip: Remember, cats don’t like their food and litterbox too close together. So place the food dishes as far away from the litter as possible within the space.


Domestic cats, especially young kittens, are known for their love of play. This behavior mimics hunting and is important in helping kittens learn to stalk, capture, and kill prey.[172] Cats also engage in play fighting, with each other and with humans. This behavior may be a way for cats to practice the skills needed for real combat, and might also reduce any fear they associate with launching attacks on other animals.[173]
After the fight, Rum Tum Tugger calls upon the magician Mr. Mistoffelees for help ("Magical Mr. Mistoffelees"). Known as the "original conjuring cat", Mr. Mistoffelees can perform feats of magic that no other cat can do. He displays his magical powers in a dance solo and uses them to restore the lights and bring back Old Deuteronomy. Now, the Jellicle Choice can be made.
Cats can be infected or infested with viruses, bacteria, fungus, protozoans, arthropods or worms that can transmit diseases to humans.[262] In some cases, the cat exhibits no symptoms of the disease,[263] However, the same disease can then become evident in a human. The likelihood that a person will become diseased depends on the age and immune status of the person. Humans who have cats living in their home or in close association are more likely to become infected, however, those who do not keep cats as pets might also acquire infections from cat feces and parasites exiting the cat's body.[262][264] Some of the infections of most concern include salmonella, cat-scratch disease and toxoplasmosis.[263]

Feeding a kitten isn’t as easy as grabbing a bag of cat chow at the nearest convenience store. Growing kittens need as much as three times more calories and nutrients than adult cats. That’s why it’s important to find a good quality food designed especially for kittens. A name brand food, formulated for kittens, is the simplest way to ensure that your kitty gets the proper nourishment without supplements. Also, check to make sure your kitten’s food includes a statement from the Association of Animal Feed Control Officials (AAFCO) displayed on the packaging, ensuring the food is nutritionally complete.
Meanwhile, the Carré Theatre in Amsterdam, Netherlands, staged the musical in 1987 (with Ruth Jacott as Grizabella[196]), 1988 and from 1992 to 1993.[197] Cats made its French debut at the Théâtre de Paris from February 1989 to April 1990,[120] with an original cast that included Gilles Ramade as Old Deuteronomy.[198] The show was also produced in Zürich at the ABB Musical Theatre from 1991 to 1993,[199] while a production by Joop van den Ende and the Royal Ballet of Flanders was staged at the Stadsschouwburg Antwerpen in Belgium in 1996.[200] An English/German-language "Eurotour" production also toured the region from May 1994 to December 1995.[174]
Felines are carnivores and have adapted to animal-based diets and low carbohydrate inclusion. Kittens are categorized in a growth life stage, and have high energy and protein requirements.[23] When feeding a kitten, it is often recommended to use highly digestible ingredients and various components to aid in development in order to produce a healthy adult.[24] In North America, diets certified by the Association of American Feed Control Officials (AAFCO) are accepted as adequate nutrition, thus kitten diets should be AAFCO approved to ensure full supplementation.[25] Key components of the diet are high fat content to meet caloric requirements of growth, high protein to meet requirements for muscle growth as well as supplementation of certain nutrients such as docosahexaenoic acid to benefit the development of the brain and optimization of cognition.[26]
Since kitten diets are very high in calories, ingredients must be implemented to ensure adequate digestion and utilization of these calories. Choline chloride is an ingredient that maintains fat metabolism.[42] Biotin and niacin are also active in the metabolism of fats, carbs and protein.[42] Riboflavin is also necessary for the digestion of fats and carbohydrates.[42] These are the main metabolism aids incorporated into kitten diets to ensure nutrient usage is maximized.
Cats have relatively few taste buds compared to humans (470 or so versus more than 9,000 on the human tongue).[91] Domestic and wild cats share a gene mutation that keeps their sweet taste buds from binding to sugary molecules, leaving them with no ability to taste sweetness.[92] Their taste buds instead respond to acids, amino acids like protein, and bitter tastes.[93] Cats also have a distinct temperature preference for their food, preferring food with a temperature around 38 °C (100 °F) which is similar to that of a fresh kill and routinely rejecting food presented cold or refrigerated (which would signal to the cat that the "prey" item is long dead and therefore possibly toxic or decomposing).[91]
The lack of readily available glucose from the limited carbohydrates in the diet has resulted to the adaptation of the liver to produce glucose from the breakdown components of protein—amino acids. The enzymes that breakdown amino acids are constantly active in cats and thus, cats need a constant source of protein in their diet.[24] Kittens, require an increased amount of protein to supply readily available amino acids for daily maintenance and for building new body components seeing as they are constantly growing.[24] There are many required amino acids for kittens. Histidine is required at no greater than 30% in kitten diets since consuming histidine-free diets causes weight loss.[25]Tryptophan is required at 0.15% seeing as it maximized performance at this level.[25] Kittens also need the following amino acids supplemented in their diet: arginine to avoid an excess of ammonia in the blood otherwise known as hyperammonemia, isoleucine, leucine, valine, lysine, methionine as a sulfur containing amino acid, asparagine for maximal growth in the early post-weaning kitten, threonine and taurine to prevent from central retinal degeneration.[25]

Reactions to the original Broadway production were mixed.[302] In his review for The New York Times, Frank Rich noted that the main draw of the show was that it "transports the audience into a complete fantasy world that could only exist in the theater". He attributed much of this "wondrous spectacle" to Nunn's direction, Napier's set and costume designs, as well as the talented cast. Rich found many of Lloyd Webber's songs to be "cleverly and appropriately" pastiche, and was impressed with how Lynne and Nunn distinguished each character through personalised movement. However, he panned Lynne's choreography and felt that the musical failed in its vague attempt to tell a story. Overall, he wished that the show had more "feeling to go with its most inventive stagecraft."[303] Clive Barnes of the New York Post concluded his review saying: "Its importance lies in its wholeheartedness. It is a statement of musical theater that cannot be ignored, should prove controversial and will never be forgotten."[304]
A cat show is a judged event in which the owners of cats compete to win titles in various cat registering organizations by entering their cats to be judged after a breed standard.[255][256] Both pedigreed and companion (or moggy) cats are admissible, although the rules differ from organization to organization. Cats are compared to a breed standard,[257] and the owners of those judged to be closest to it are awarded a prize. Moggies are judged based on their temperament. Often, at the end of the year, all of the points accrued at various shows are added up and more national and regional titles are awarded.
Cats are unusually dependent on a constant supply of the amino acid arginine, and a diet lacking arginine causes marked weight loss and can be rapidly fatal.[115] Arginine is an essential additive in cat food because cats have low levels of the enzymes aminotransferase and pyrroline-5-carboxylate which are responsible for the synthesis of ornithine and citrulline in the small intestine. Citrulline would typically go on to the kidneys to make arginine, but because cats have a deficiency in the enzymes that make it, citrulline is not produced in adequate quantities to make arginine. Arginine is essential in the urea cycle in order to convert the toxic component ammonia into urea that can then be excreted in the urine. Because of its essential role, deficiency in arginine results in a buildup of toxic ammonia and leads to hyperammonemia.[116] The symptoms of hyperammonemia include lethargy, vomiting, ataxia, hyperesthesia and can be serious enough to induce death and coma in a matter of days if a cat is being fed an arginine-free diet. The quick onset of these symptoms is due to the fact that diets devoid in arginine will typically still contain all of the other amino acids, which will continue to be catabolized by the body, producing mass amounts of ammonia that very quickly build up with no way of being excreted.[citation needed]
Spanish and Portuguese-language productions of Cats have been staged in South America, with productions in Argentina in 1993 (with Olivia Bucio as Grizabella),[177] in Chile in 2006 (at the Arena Santiago)[271] and 2014,[272] in Colombia in 2009,[273] and in Brazil in 2010 (with Paula Lima as Grizabella).[274] Other countries that the musical has been performed in include South Africa (2001–2002),[250] Lebanon (2002),[275] Qatar (2003, 2017),[276][277] Turkey (2013),[278] Israel (2014),[279] and the United Arab Emirates (2017).[280]
Cats are popular as a subject of art and photography, Walter Chandoha made his career photographing cats after his 1949 images of Loco, an especially charming stray taken in, were published around the world. He is reported to have photographed 90,000 cats during his career and maintained an archive of 225,000 images that he drew from for publications during his lifetime.[254]
Cats has received many international awards and nominations. The original London production was nominated for six Laurence Olivier Awards in 1981, winning two awards including Best New Musical.[306] Two years later, the original Broadway production won seven Tony Awards, including Best Musical, out of eleven nominations.[307] The London and Broadway cast recordings were nominated for the Grammy Award for Best Musical Theater Album, which the latter won.[308][309] In 2015, the London revival was nominated for — but did not win — two Olivier Awards, including Best Musical Revival.[310]

The London production ran for 21 years and 8,949 performances, while the Broadway production ran for 18 years and 7,485 performances, making Cats the longest-running musical in both theatre districts for a number of years. As of 2019, it remains the sixth-longest-running West End show and the fourth-longest-running Broadway show. Cats has since been revived in the West End twice and on Broadway once. It has also been translated into multiple languages and performed around the world many times. Long-running foreign productions include a 15-year run at the Operettenhaus in Hamburg that played over 6,100 performances, as well as an ongoing run in a purpose-built theatre in Japan that has played over 10,000 performances since it opened in 1983.
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 stage production of Cats has undergone several revisions since its London opening. When the show transferred to Broadway, several cuts and rewrites were made with the intention of appealing more to an American audience.[385] Additionally, a song entitled "Cat Morgan Introduces Himself" was cut during initial development. Lloyd Webber performed this song at the show's 6,138th Broadway performance, when it broke the record to become the longest-running Broadway show.[105]
During a fall from a high place, a cat reflexively twists its body and rights itself to land on its feet using its acute sense of balance and flexibility. This reflex is known as the cat righting reflex.[96] An individual cat always rights itself in the same way during a fall, provided it has sufficient time to do so. The height required for this to occur is around 90 cm (3.0 ft).[97] Cats without a tail also have this reflex.[98] Several explanations have been proposed for this phenomenon since the late 19th century:
