Cats have seven cervical vertebrae (as do most mammals); 13 thoracic vertebrae (humans have 12); seven lumbar vertebrae (humans have five); three sacral vertebrae (as do most mammals, but humans have five); and a variable number of caudal vertebrae in the tail (humans have only vestigial caudal vertebrae, fused into an internal coccyx).:11 The extra lumbar and thoracic vertebrae account for the cat's spinal mobility and flexibility. Attached to the spine are 13 ribs, the shoulder, and the pelvis. :16 Unlike human arms, cat forelimbs are attached to the shoulder by free-floating clavicle bones which allow them to pass their body through any space into which they can fit their head.
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. 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. From 1989 to 1990, the company toured the Festival Theatre in Adelaide, His Majesty's Theatre in Perth, Civic Theatre in Newcastle, Lyric Theatre in Brisbane, and the Aotea Centre in Auckland. This was followed by a second national tour from 1993 to 1996, during which Delia Hannah made her debut as Grizabella in 1994. 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. Hannah reprised her role for another production that toured Australia and Asia in 2009 and 2010.
The origin of the English word cat (Old English catt) and its counterparts in other Germanic languages (such as German Katze), descended from Proto-Germanic *kattōn-, is controversial. It was thought traditionally to be a borrowing from Late Latin cattus, 'domestic cat', from catta (used around 75 AD by Martial), compare also Byzantine Greek κάττα, Portuguese and Spanish gato, French chat, Maltese qattus, Lithuanian katė, and Old Church Slavonic kotъ (kot'), among others.
Lloyd Webber began setting Eliot's poems to music in 1977 and the compositions were first presented as a song cycle in 1980. Producer Cameron Mackintosh then recruited director Trevor Nunn and choreographer Gillian Lynne to turn the songs into a complete musical. Cats opened to positive reviews at the New London Theatre in the West End in 1981 and then to mixed reviews at the Winter Garden Theatre on Broadway in 1982. It won numerous awards including Best Musical at both the Laurence Olivier and Tony Awards. Despite its unusual premise which deterred investors initially, the musical turned out to be an unprecedented commercial success, with a worldwide gross of $3.5 billion by 2012.
The domestic cat is a member of the Felidae, a family that had a common ancestor about 10–15 million years ago. The genus Felis diverged from the Felidae around 6–7 million years ago. Members of this genus include the jungle cat (F. chaus), European wildcat (F. silvestris), African wildcat (F. lybica), Chinese mountain cat (F. bieti), sand cat (F. margarita) and black-footed cat (F. nigripes). Results of phylogenetic research confirm that these wild Felis species evolved through sympatric or parapatric speciation, whereas the domestic cat evolved through artificial selection.
Following its Broadway debut, Cats has been staged extensively across North America. The first US national tour, Cats National I, launched at the Shubert Theatre in Boston in December 1983 and closed in November 1987. The opening night cast included Laurie Beechman playing Grizabella and Charlotte d'Amboise playing Cassandra; later replacements included Victoria Clark and Jessica Molaskey both playing Jellylorum/Griddlebone. This production was a "slow tour" that had lengthy engagements lasting for several months in each of the nine cities it visited. Cats National II, a separate sit-down production at the Los Angeles Shubert Theatre, ran from January 1985 to November 1986, and starred Kim Criswell and George de la Peña in the roles of Grizabella and Mistoffelees respectively. A third US touring company, Cats National III, ran for two years from September 1986 to September 1988. Notable performers in the third tour included Jonathan Cerullo as Skimbleshanks (1986) and Bill Nolte as Old Deuteronomy (1987).
The Late Latin word is generally thought to originate from an Afro-Asiatic language, but every proposed source word has presented problems. Many references refer to "Berber" (Kabyle) kaddîska, 'wildcat', and Nubian kadīs as possible sources or cognates, but M. Lionel Bender suggests the Nubian term is a loan from Arabic قِطَّة qiṭṭa. Jean-Paul Savignac suggests the Latin word is from an Ancient Egyptian precursor of Coptic ϣⲁⲩ šau, 'tomcat', or its feminine form suffixed with -t, but John Huehnergard says "the source [...] was clearly not Egyptian itself, where no analogous form is attested." Huehnergard opines it is "equally likely that the forms might derive from an ancient Germanic word, imported into Latin and thence to Greek and to Syriac and Arabic". Guus Kroonen also considers the word to be native to Germanic (due to morphological alternations) and Northern Europe, and suggests that it might ultimately be borrowed from Uralic, cf. Northern Sami gáđfi, 'female stoat', and Hungarian hölgy, 'stoat'; from Proto-Uralic *käďwä, 'female (of a furred animal)'. In any case, cat is a classic example of a word that has spread as a loanword among numerous languages and cultures: a Wanderwort.
