Practical Cats, as the show was then called, was first presented as a song cycle at the 1980 summer Sydmonton Festival. The concert was performed by Gemma Craven, Gary Bond and Paul Nicholas. Eliot's widow and literary executor, Valerie, was in attendance and brought along various unpublished cat-themed poems by Eliot. One of these was "Grizabella the Glamour Cat" which, although rejected from Eliot's book for being "too sad for children", gave Lloyd Webber the idea for a full-blown musical.[10] He explained:

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.

Some of the same factors that have promoted adaptive radiation of island avifauna over evolutionary time appear to promote vulnerability to non-native species in modern time. The susceptibility of many island birds is undoubtedly due to evolution in the absence of mainland predators, competitors, diseases, and parasites, in addition to lower reproductive rates and extended incubation periods.[231] The loss of flight, or reduced flying ability is also characteristic of many island endemics.[232] These biological aspects have increased vulnerability to extinction in the presence of introduced species, such as the domestic cat.[233] Equally, behavioral traits exhibited by island species, such as "predatory naivety"[234] and ground-nesting,[231] have also contributed to their susceptibility.
Public attitudes towards feral cats vary widely, ranging from seeing them as free-ranging pets, to regarding them as vermin.[208] One common approach to reducing the feral cat population is termed 'trap-neuter-return', where the cats are trapped, neutered, immunized against diseases such as rabies and the feline Panleukopenia and Leukemia viruses, and then released.[209] Before releasing them back into their feral colonies, the attending veterinarian often nips the tip off one ear to mark it as neutered and inoculated, since these cats may be trapped again. Volunteers continue to feed and give care to these cats throughout their lives. Given this support, their lifespans are increased, and behavior and nuisance problems caused by competition for food are reduced.[206]

The first Australian production ran from July 1985 to August 1987 at the Theatre Royal in Sydney. The original Sydney cast included Debra Byrne as Grizabella, Marina Prior as Jellylorum, Jeff Phillips as Rum Tum Tugger, David Atkins as Mistoffelees, and Anita Louise Combe as Sillabub.[118][230] It then moved to Her Majesty's Theatre in Melbourne where it played from October 1987 to December 1988, with Femi Taylor as Bombalurina and Seán Martin Hingston as Plato/Macavity.[118][231] From 1989 to 1990, the company toured the Festival Theatre in Adelaide,[232] His Majesty's Theatre in Perth,[233] Civic Theatre in Newcastle, Lyric Theatre in Brisbane, and the Aotea Centre in Auckland.[118] This was followed by a second national tour from 1993 to 1996,[234] during which Delia Hannah made her debut as Grizabella in 1994.[235] A professional circus adaptation of Cats, titled Cats Run Away to the Circus, had a national tent tour from 1999 to 2001, with Hannah once again starring as Grizabella.[236][237] Hannah reprised her role for another production that toured Australia and Asia in 2009 and 2010.[238]

The musical has also been translated and staged nationally in Asia. From September 2008 to January 2009, a Korean-language production performed at the Charlotte Theatre in Seoul, with Shin Youngsook and Ock Joo-hyun alternating as Grizabella, Kim Jin-woo and Daesung alternating as Rum Tum Tugger, and Kim Bo-kyung as Rumpleteazer.[268] This production was revived and toured South Korea from 2011 to 2012, with Insooni and Park Hae-mi taking turns to portray Grizabella.[269] The first Mandarin-language production toured various cities in China in 2012.[270]

Napier began designing the set in November 1980, wanting "a place where cats might congregate together, which also included maximum room for dancing".[93] The set of Cats consists of a junkyard filled with oversized props to give the illusion that the cast are the size of actual cats;[94] it remains the same throughout the show without any scene changes. Over 2,500 of these scaled-up props were used to fill the whole auditorium in the original Broadway production.[16][95]

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]
Despite moderate hits with Jesus Christ Superstar and Evita, Lloyd Webber was still relatively unknown to the general public before Cats, especially in the US. With Cats, he became a big celebrity in his own right.[318] The musical also established the theatrical careers of the original creative and production team. Following Cats, they collaborated on other global blockbusters including Starlight Express (composed by Lloyd Webber, directed by Nunn and designed by Napier), Les Misérables (directed by Nunn, designed by Napier and produced by Mackintosh), and The Phantom of the Opera (composed by Lloyd Webber, choreographed by Lynne and produced by Mackintosh).[1][335]
Atlas Games has been creating games for nearly three decades. We have launched, completed, and fulfilled four previous Kickstarter projects: Feng Shui 2, Unknown Armies 3, the third edition of Over the Edge, and the exciting card game Cogs & Commissars. While every project comes with its own special risks and demands, we’re confident that Magical Kitties Save the Day will be every bit as successful in its production and fulfillment as these other games.
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]

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]
Here in eight lines Eliot was describing an intensely recognizable character with powerful human resonances, while introducing the themes of mortality, and the past, which occur repeatedly in the major poems. We decided that if Eliot had thought of being serious, touching, almost tragic in his presentation of a feline character, then we had to be doing a show which could contain that material, and the implications of it. Furthermore, we would have to achieve the sense of progression through themes more than incidents.[17]

Old Possum's Book of Practical Cats is a collection of light poetry about cats that Eliot had originally written for his godchildren in the 1930s. Due to the rhythmic nature of Eliot's work, there had been previous attempts before Cats at setting his poems to music, though none of these attempts had been met with much critical or commercial success.[6] Musicologist John Snelson wrote of the poems:

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.
The earliest known indication for a tamed African wildcat was excavated close by a human grave in Shillourokambos, southern Cyprus, dating to about 9,200 to 9,500 years before present. As there is no evidence of native mammalian fauna on Cyprus, the inhabitants of this Neolithic village most likely brought the cat and other wild mammals to the island from the Middle Eastern mainland.[13] Scientists therefore assume that African wildcats were attracted to early human settlements in the Fertile Crescent by rodents, in particular the house mouse (Mus musculus), and were tamed by Neolithic farmers. This commensal relationship between early farmers and tamed cats lasted thousands of years. As agricultural practices spread, so did tame and domesticated cats.[14][6] Wildcats of Egypt contributed to the maternal gene pool of the domestic cat at a later time.[49] The earliest known evidence for the occurrence of the domestic cat in Greece dates to around 1200 BC. Greek, Phoenician, Carthaginian and Etruscan traders introduced domestic cats to southern Europe.[50] By the 5th century BC, it was a familiar animal around settlements in Magna Graecia and Etruria.[51] Domesticated cats were introduced to Corsica and Sardinia during the Roman Empire before the beginning of the 1st millennium.[52] The Egyptian domestic cat lineage is evidenced in a Baltic Sea port in northern Germany by the end of the Roman Empire in the 5th century.[49]
