Reactions to the original Broadway production were mixed. 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." 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."
Until approximately one year of age, the kitten is undergoing a growth phase where energy requirements are up to 2.5 times higher than maintenance. Pet nutritionists often suggest that a commercial cat food designed specifically for kittens should be offered beginning at 4 weeks of age. Fat has a higher caloric value than carbohydrates and protein, supplying 8.5kcal/g. The growing kitten requires arachidonic and linoleic acid which can be provided in omega-3 fatty acids. Docosahexaenoic acid (DHA) is another vital nutrient that can be supplied through omega 3 fatty acid. Addition of DHA to the diet benefits the cognition, brain and visual development of kittens.
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. 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. 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.
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.
