Female cats are seasonally polyestrous, which means they may have many periods of heat over the course of a year, the season beginning in spring and ending in late autumn. Heat periods occur about every two weeks and last about 4 to 7 days.[178] Multiple males will be attracted to a female in heat. The males will fight over her, and the victor wins the right to mate. At first, the female rejects the male, but eventually the female allows the male to mate. The female utters a loud yowl as the male pulls out of her because a male cat's penis has a band of about 120–150 backwards-pointing penile spines, which are about 1 mm long; upon withdrawal of the penis, the spines rake the walls of the female's vagina, which acts to induce ovulation. This act also occurs to clear the vagina of other sperm in the context of a second (or more) mating, thus giving the later males a larger chance of conception.[179]
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".
In Magical Kitties Save the Day, one player — known as the Game Master (GM) — has a very special role. They describe the world in which the magical kitties live to the other players and, when the kitties take action, they use the rules of the game to figure out what happens next. Magical Kitties also includes “Magical Kitties & The Game Master’s First Adventure.” Just as The Big Adventure will walk new players through how to play the game, “The Game Master’s First Adventure” will walk first-time Game Masters through how to run the game for their friends and family.

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]
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]

Feral cats are domestic cats that were born in or have reverted to a wild state. They are unfamiliar with and wary of humans and roam freely in urban and rural areas.[10] The numbers of feral cats is not known, but estimates of the US feral population range from 25 to 60 million.[10] Feral cats may live alone, but most are found in large colonies, which occupy a specific territory and are usually associated with a source of food.[206] Famous feral cat colonies are found in Rome around the Colosseum and Forum Romanum, with cats at some of these sites being fed and given medical attention by volunteers.[207]
Before Old Deuteronomy can announce his decision, Grizabella returns to the junkyard and he allows her to address the gathering. Her faded appearance and lonely disposition have little effect on her song ("Memory"). With acceptance and encouragement from Jemima and Victoria, her appeal succeeds and she is chosen to be the one to go to the Heaviside Layer and be reborn into a new Jellicle life ("Journey to the Heaviside Layer"). A tyre rises from the piles of junk, carrying Grizabella and Old Deuteronomy partway toward the sky; Grizabella then completes the journey on her own.[i] Finally, Old Deuteronomy gives his closing speech to the audience ("The Ad-dressing of Cats") and the show comes to a close.
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]
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]

Many of the ensemble characters were created by the original cast through extensive improvisation sessions held during the rehearsal process. Said Nunn: "[O]n day one of rehearsals what we had was 15 poems set to music and five weeks later we had a show with characters, relationships and stories running from beginning to end."[24][25] The production faced a last minute mishap when Dench snapped her Achilles tendon during rehearsals for "The Old Gumbie Cat" and had to pull out one week before the first preview. Her understudy Myra Sands replaced her as Jennyanydots, while Elaine Paige agreed to take over the role of Grizabella. Opening night was pushed back to 11 May, but Mackintosh refused to postpone the previews as he wanted to dispel the industry rumours that the production was an impending debacle.[26]
Cats, like dogs, are digitigrades. They walk directly on their toes, with the bones of their feet making up the lower part of the visible leg.[69] Cats are capable of walking very precisely because, like all felines, they directly register; that is, they place each hind paw (almost) directly in the print of the corresponding fore paw, minimizing noise and visible tracks. This also provides sure footing for their hind paws when they navigate rough terrain. Unlike most mammals, when cats walk, they use a "pacing" gait; that is, they move the two legs on one side of the body before the legs on the other side. This trait is shared with camels and giraffes. As a walk speeds up into a trot, a cat's gait changes to be a "diagonal" gait, similar to that of most other mammals (and many other land animals, such as lizards): the diagonally opposite hind and fore legs move simultaneously.[70]
In July 2014, Australia's Harvest Rain Theatre Company staged the biggest production of Cats in the Southern Hemisphere with over 700 performers. Produced by Tim O'Connor, the production was performed at the Brisbane Convention & Exhibition Centre. Callum Mansfield directed and choreographed it, and its cast included Marina Prior as Grizabella and Steven Tandy as Bustopher Jones and Gus.[239][240] From October 2015 to May 2016, a revival toured Australia with stops in Sydney, Hobart, Melbourne, Brisbane, Adelaide, and Perth.[241][242] The revival featured singer-songwriter Delta Goodrem as Grizabella,[243] before Delia Hannah took over the role during the Adelaide and Perth seasons.[235][244]

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 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 musical was scheduled to open on 30 April 1981, with previews starting on 22 April. Shortly before tickets went on sale in mid-February, Nunn revealed to the alarmed producers that he was struggling to write the script for the musical. Despite still having no established book or score, rehearsals began on 9 March 1981 in a church hall in Chiswick, London. The original music director, Chris Walker, became so frustrated with the unfinished score that he quit by lunchtime and was replaced by the film conductor Harry Rabinowitz.[20] The situation improved later that day when Lloyd Webber, Mackintosh and Nunn met with Stilgoe, a musician known for his ability to improvise lyrics on the spot, in hopes that Stilgoe could write an opening song for the musical. By the next evening, Stilgoe had produced a draft for "Jellicle Songs for Jellicle Cats".[21] However, "Memory", an 11 o'clock number for Grizabella that Nunn insisted the show needed as its "emotional centre",[22] still had no lyrics at this point. Lloyd Webber's former writing partner Tim Rice was brought in to write a lyric for the song, but his version was rejected by Nunn for being too depressing. The lyrics for "Memory" were not completed by Nunn until well into the previews.[23]

The domestic cat's ability to thrive in almost any terrestrial habitat has led to its designation as one of the world's most invasive species.[203] As it is little altered from the wildcat, it can readily interbreed with the wildcat. This hybridization poses a danger to the genetic distinctiveness of some wildcat populations, particularly in Scotland and Hungary and possibly also the Iberian Peninsula.[56]
In isolated landmasses, such as Australasia, there are often no other native, medium-sized quadrupedal predators (including other feline species); this tends to exacerbate the impact of feral cats on small native animals.[214] Native species such as the New Zealand kakapo and the Australian bettong, for example, tend to be more ecologically vulnerable and behaviorally "naive", when faced with predation by cats.[215] Feral cats have had a major impact on these native species and have played a leading role in the endangerment and extinction of many animals.[216]

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.

The gestation period of queens is between 64 and 67 days, with an average of 66 days.[183] Data on reproductive capacity of more than 2,300 free-ranging queens were collected during a study between May 1998 and October 2000. They had one to six kittens per litter, with an average of three kittens. They produced a mean of 1.4 litters per year, but a maximum of three litters in a year. Of 169 kittens, 127 died before they were six months old due to a trauma caused in most cases by dog attacks and road accidents.[9] The first litter is usually smaller than subsequent litters. Kittens are weaned between six and seven weeks of age. Queens normally reach sexual maturity at 5–10 months, and males at 5–7 months. This varies depending on breed.[178]
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.
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]
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]
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]

Napier also designed the costumes, combining cat and human features based on "hints" given in Eliot's poems, while ensuring that they did not impede the dancers' movements.[93] The costumes generally consist of a unitard, a wig that is fashioned to suggest the presence of feline ears, patches resembling body fur, and arm and leg warmers to give the performers' hands and feet a more paw-like appearance. As with the contrasting music and dance styles, the costumes and make-up are used to bring out each character's distinct personality. For example, the costume for the flirtatious Bombalurina is designed to accentuate her sexiness, while the markings on the costume for Jemima — the youngest of the tribe — resemble crayon scribbles.[24] Every character's design motif is custom-painted by hand onto a plain unitard to line up with their performer's individual body. In order to reproduce the "hand-drawn aesthetic" of Napier's original design sketches, costume painters in the original Broadway production used squeeze bottles to apply the paint. Due to the amount of dancing in Cats, most of the costume did not last longer than a few months.[96]
Feral cats can live in forests, grasslands, tundra, coastal areas, agricultural land, scrublands, urban areas, and wetlands.[204] Their habitats include small islands with no human inhabitants.[205] The close relatives of the domestic cat, the African wildcat (Felis lybica) and the sand cat (F. margarita) both inhabit desert environments.[42] Domestic cats still show similar adaptations and behaviors.[103]
Kittens develop very quickly from about two weeks of age until their seventh week. Their coordination and strength improves. They play-fight with their litter-mates and begin to explore the world outside the nest or den. They learn to wash themselves and others as well as play hunting and stalking games, showing their inborn ability as predators. These innate skills are developed by the kittens' mother or other adult cats, who bring live prey to the nest. Later, the adult cats demonstrate hunting techniques for the kittens to emulate.[11] As they reach three to four weeks old, the kittens are gradually weaned and begin to eat solid food, with weaning usually complete by six to eight weeks.[12] Kittens generally begin to lose their baby teeth around three months of age, and have a complete set of adult teeth by nine months.[13] Kittens live primarily on solid food after weaning, but usually continue to suckle from time to time until separated from their mothers. Some mother cats will scatter their kittens as early as three months of age, while others continue to look after them until they approach sexual maturity.[14]
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]

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]
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]

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.
