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]

One of Nunn's stipulations for agreeing to direct Practical Cats was that actress Judi Dench would be cast in the musical. Lloyd Webber was happy to oblige given her credentials and so Dench joined the company in the dual roles of Grizabella and Jennyanydots. Former Royal Ballet principal dancer Wayne Sleep was offered the part of Mr. Mistoffelees after Lloyd Webber and Mackintosh attended a performance by his dance troupe, one of the many dance showcases they saw in preparation for the musical. Casting for the other roles began in November 1980, with auditions held across the UK for dancers who could also sing and act. There was an initial disagreement over the casting of Nicholas as Rum Tum Tugger; Nunn had misgivings about the actor's laid-back attitude but eventually yielded to Lloyd Webber, Mackintosh and Lynne, all of whom were keen on Nicholas for the role. Sarah Brightman, who had already made a name for herself with the chart hit "I Lost My Heart to a Starship Trooper", arranged a private audition and was cast in an as-then undecided role. By December, the full cast had been assembled.[18]
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.
Another unusual feature is that the cat cannot produce taurine,[note 1] with a deficiency in this nutrient causing macular degeneration, wherein the cat's retina slowly breaks down, causing irreversible blindness.[103] This is due to the hepatic activity of cystinesulfinic acid decarboxylase being low in cats. This limits the ability of cats to biosynthesize the taurine they need from its precursor, the amino acid cysteine, which ultimately results in inadequate taurine production needed for normal function. Deficiencies in taurine result in compensated function of feline cardiovascular and reproductive systems. These abnormalities can also be accompanied by developmental issues in the central nervous system along with degeneration of the retina.[118]

After the show's closure on Broadway in 2000, Troika Entertainment obtained the touring rights for Cats and launched the show's first non-Equity national company.[119] After a try-out at Harrah's Atlantic City in July 2001, the production toured North America for 11 years from August 2001 to June 2012.[120][121][122] Performers in the non-Equity tour included Julie Garnyé as Jennyanydots (2001)[123] and Dee Roscioli as Grizabella (2002).[124][125] In January 2019, a new North American Equity tour based on the 2016 Broadway revival opened at the Providence Performing Arts Center in Rhode Island,[126] and is scheduled to run through June 2020.[127]
Life in proximity to humans and other domestic animals has led to a symbiotic social adaptation in cats, and cats may express great affection toward humans or other animals. Ethologically, the human keeper of a cat may function as a sort of surrogate for the cat's mother,[136] and adult housecats live their lives in a kind of extended kittenhood,[137] a form of behavioral neoteny. The high-pitched sounds housecats make to solicit food may mimic the cries of a hungry human infant, making them particularly difficult for humans to ignore.[138]
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]

Vitamin A is required in kitten diets because cats cannot convert carotenes to retinol in the intestinal mucosa because they lack the enzyme so this vitamin must be supplement in the diet.[24][42] Vitamin E is another required vitamin in kitten diets seeing as deficiency leads to steatitis, causing the depot fat to become firm and yellow-orange in colour, which is painful and leads to death.[42] Also, vitamin D is an essential vitamin because cats cannot convert it from precursors in the skin.[24]

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]
Taurine is an essential amino acid found only in animal tissues and cannot be produced in sufficient amounts by the cat.[36] As it is an indispensable amino acid, it must be provided exogenously through the diet at 10 mg/kg bodyweight/day.[37] Kittens deprived of taurine can experience poor growth[36] and can result in retinal degeneration in cats.[38]
Owing to the close similarity between play and hunting, cats prefer to play with objects that resemble prey, such as small furry toys that move rapidly, but rapidly lose interest (they become habituated) in a toy they have played with before.[174] Cats also tend to play with toys more when they are hungry.[175] String is often used as a toy, but if it is eaten, it can become caught at the base of the cat's tongue and then move into the intestines, a medical emergency which can cause serious illness, even death.[176] Owing to the risks posed by cats eating string, it is sometimes replaced with a laser pointer's dot, which cats may chase.[177]
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]

Cats are naturally carnivores and require high amounts of protein in the diet. Kittens are undergoing growth and require high amounts of protein to provide essential amino acids that enable the growth of tissues and muscles.[30] It is recommended that kittens consume a diet containing approximately 30% protein on a dry matter basis for proper growth.[35]


Beyond the megamusical, Cats also led the Broadway trend for musicals aimed at families and tourists, which would later take the form of the Disney Theatrical Productions and jukebox musicals.[315][324] The marketing campaigns for the musical targeted family audiences at a time when this demographic was not a consideration in the industry.[324] Composer Joe Raposo said of family musicals in 1986: "Cats is a wonderful proof of what an audience is out there, untapped. People do want a theatrical experience for their children."[325] Thanks to its easily accessible spectacle, the original Broadway production also tapped into the then-burgeoning tourist boom in New York and its audience shifted increasingly towards foreign visitors in its later years.[321][314] Billington also specifically traces the rise of the jukebox musical genre back to Cats, citing the latter's disregard for dramatic text in favour of an all-encompassing theatrical experience.[326]

With a third crash and an evil laugh, the "most wanted" cat Macavity appears. He is the so-called "Napoleon of Crime" who always manages to evade the authorities. Macavity's henchmen capture Old Deuteronomy and take off with the patriarch in tow. As Munkustrap and his troops give chase, Demeter and Bombalurina explain what they know about Macavity ("Macavity: The Mystery Cat"). When they are finished, Macavity returns disguised as Old Deuteronomy, but his cover is blown by Demeter and he ends up in a fight with Munkustrap and Alonzo. Macavity holds his own for a time, but as the rest of the tribe begin to gang up and surround him, he shorts out the stage lights and escapes in the resulting confusion.


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]

The first UK and Ireland tour opened in May 1989 at the Opera House Theatre in Blackpool. The cast for this tour included Marti Webb as Grizabella, Rosemarie Ford as Bombalurina and John Partridge as Alonzo.[120] Following a six-month engagement in Blackpool that broke the theatre's box office record and was seen by around 450,000 people,[142] the production moved to the Edinburgh Playhouse for three months, before closing in May 1990 after another two months at the Point Theatre in Dublin.[120] A second national tour launched in June 1993 at the Bristol Hippodrome,[143] featuring Rosemarie Ford as Grizabella, Robin Cousins as Munkustrap, Simon Rice as Mistoffelees and Tony Monopoly as Old Deuteronomy.[144] The tour closed at the Manchester Opera House in December 1995.[145]
Cats has been produced by various professional regional theatre companies. Broadway Sacramento staged the musical in 2003 and 2009 at the Wells Fargo Pavilion. Both productions featured Ken Page reprising his role as Old Deuteronomy from the original Broadway production, along with Jacquelyn Piro Donovan as Grizabella and Jeffry Denman as Munkustrap.[283][284] A 2010 amphitheatre production at The Muny starred Page as Old Deuteronomy, Stephanie J. Block as Grizabella and Lara Teeter as Munkustrap.[285] The La Mirada Theatre for the Performing Arts staged the musical in 2014, with a cast that included Todrick Hall as Rum Tum Tugger.[286]

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]

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]

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".

Cats is based on T. S. Eliot's 1939 poetry book Old Possum's Book of Practical Cats, with the songs in the musical consisting of Eliot's verse set to music by Andrew Lloyd Webber.[1] The musical is unusual in terms of its construction; along with Eliot's poems, music and dance are the main focus of the show at the expense of a traditional narrative structure.[2] Musicologists William Everett and Paul Laird described Cats as "combining elements of the revue and concept musical".[3] The plot centres on a tribe of cats called the Jellicles, as they come together at the annual Jellicle Ball to decide which one of them will ascend to the Heaviside Layer (their version of heaven) and be reborn into a new life.[4] The bulk of the musical consists of the different contenders being introduced, either by themselves or by other cats.[5]
In the original London production, Mungojerrie and Rumpleteazer were characters in their own right and sang their eponymous song themselves as a singsong-style duet. When the show transferred to Broadway, the song was instead sung in the third-person, with Mungojerrie and Rumpleteazer as puppets being magically controlled by Mr. Mistoffelees. Their number was also rewritten to be faster and more upbeat, alternating between vaudeville-style verses and a "manic patter" section. Eventually, the Broadway version of the song was rewritten to allow Mungojerrie and Rumpleteazer to once again sing their own song as full characters.[388]

When cats become aggressive, they try to make themselves appear larger and more threatening by raising their fur, arching their backs, turning sideways and hissing or spitting.[141] Often, the ears are pointed down and back to avoid damage to the inner ear and potentially listen for any changes behind them while focused forward. They may also vocalize loudly and bare their teeth in an effort to further intimidate their opponent. Fights usually consist of grappling and delivering powerful slaps to the face and body with the forepaws as well as bites. Cats also throw themselves to the ground in a defensive posture to rake their opponent's belly with their powerful hind legs.[152]

Most of the lyrics in Cats were taken from Old Possum's Book of Practical Cats with very minor alterations. Supplementary verses from unpublished poems by Eliot were adapted for "Grizabella: The Glamour Cat" and "Journey to the Heaviside Layer", while the song "The Moments of Happiness" was taken from a passage in Eliot's The Dry Salvages. Cats director Trevor Nunn and lyricist Richard Stilgoe provided the remaining lyrics, namely for the opening number "Jellicle Songs for Jellicle Cats" and the most famous song from the musical "Memory". The former was written by Nunn and Stilgoe and was modelled after an unpublished poem by Eliot titled "Pollicle Dogs and Jellicle Cats", while the latter was written by Nunn based on another Eliot poem titled "Rhapsody on a Windy Night".[1]
A few attempts to build a cat census have been made over the years, both through associations or national and international organizations (such as the Canadian Federation of Humane Societies's one[245]) and over the Internet,[246][247] but such a task does not seem simple to achieve. General estimates for the global population of domestic cats range widely from anywhere between 200 million to 600 million.[248][249][250][251][252][253]
The original staging of Cats at the New London Theatre was considered revolutionary[85] and "one of the first truly immersive theatrical experiences".[34] Instead of a conventional proscenium, the theatre was quasi-in-the-round with a central revolving stage.[15][86] Nunn and Napier had sought to create "an environment rather than a set",[17] and around $900,000 was spent remodelling the New London in preparation for the show.[9] This included mounting sections of the stalls onto the theatre's 60 ft (18 m)[87] revolve such that the audience moved along with the stage.[16] When the show was brought to Broadway, the Winter Garden Theatre was given a similar $2 million makeover;[88] its proscenium stage was converted into a thrust, and a part of its roof was torn through to allow for the effects of Grizabella's ascension to the Heaviside Layer.[89]

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]

By 2012, the royalty payments from Cats to the Eliot estate had totaled an estimated $100 million.[294] Valerie Eliot used a portion of this money to establish the literary charity Old Possum's Practical Trust, and to set up the T. S. Eliot Prize which has since become "the most coveted award in poetry".[337][338] Cats also turned things around for the independent British publishing house Faber and Faber. As the publisher of Old Possum's Book of Practical Cats, royalties of up to £1 million annually[316] kept the then-struggling Faber afloat during the 1980s.[339] Moreover, the musical led to a surge in the sales of Eliot's book.[1] The success of Cats led Faber to turn another of their literary properties, Ted Hughes' The Iron Man, into a 1989 musical of the same name.[340]

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]
Part of the kitten's immune system is the mucosal immune system, which is within the gastrointestinal tract. The mucosal immune system is largely responsible for coordinating proper immune responses by tolerating innocuous antigens and attacking foreign pathogens.[27] In order to optimize kitten health and increase chances of survival, it is important to optimize the link between the gut-associated lymphoid tissue and the microbiota of the gastrointestinal tract. Lasting health and longevity can be accomplished partly through proper nutrition[28] and establishing a healthy gut from birth through utilizing colostrum.[29]
Preformed vitamin A is required in the cat for retinal and reproductive health. Vitamin A is considered to be a fat-soluble vitamin and is seen as essential in a cat's diet. Normally, the conversion of beta-carotenes into vitamin A occurs in the intestine (more specifically the mucosal layer) of species, however cats lack the ability to undergo this process.[121] Both the kidney and liver are contributors to the use of vitamin A in the body of the majority of species while the cats liver does not produce the enzyme Beta-carotene 15,15'-monooxygenase which converts the beta-carotene into retinol (vitamin A).[122] To summarize: cats do not have high levels of this enzyme leading to the cleavage and oxidation of carotenoids not taking place.[120]
