Felines are carnivores and have adapted to animal-based diets and low carbohydrate inclusion. Kittens are categorized in a growth life stage, and have high energy and protein requirements. When feeding a kitten, it is often recommended to use highly digestible ingredients and various components to aid in development in order to produce a healthy adult. In North America, diets certified by the Association of American Feed Control Officials (AAFCO) are accepted as adequate nutrition, thus kitten diets should be AAFCO approved to ensure full supplementation. Key components of the diet are high fat content to meet caloric requirements of growth, high protein to meet requirements for muscle growth as well as supplementation of certain nutrients such as docosahexaenoic acid to benefit the development of the brain and optimization of cognition.
A kitten is a juvenile cat. After being born, kittens are totally dependent on their mother for survival and they do not normally open their eyes until after seven to ten days. After about two weeks, kittens quickly develop and begin to explore the world outside the nest. After a further three to four weeks, they begin to eat solid food and grow adult teeth. Domestic kittens are highly social animals and usually enjoy human companionship.

Free-fed feral cats and house cats tend to consume many small meals in a single day, although the frequency and size of meals varies between individuals. Cats use two hunting strategies, either stalking prey actively, or waiting in ambush until an animal comes close enough to be captured. Although it is not certain, the strategy used may depend on the prey species in the area, with cats waiting in ambush outside burrows, but tending to actively stalk birds.:153
Cats have relatively few taste buds compared to humans (470 or so versus more than 9,000 on the human tongue). 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. Their taste buds instead respond to acids, amino acids like protein, and bitter tastes. 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).
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. 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.
Cats introduced a marketing strategy that set the template for subsequent megamusicals. Early advertisements for the musical did not feature traditional pull quotes (despite many positive reviews) or any of the cast, focusing instead on branding the show itself as the star. It did this by adopting — and then aggressively promoting — a single recognisable image (the cat's-eyes logo) as the face of the show. The cat's-eyes logo was the first globally marketed logo in musical theatre history, and was paired with a tagline ("now and forever") to create what The Daily Telegraph called "one of musical theatre's greatest posters". Such branding emblems proved equally effective for later megamusicals, as seen with the waif Cosette for Les Misérables and the Phantom's mask for The Phantom of the Opera. This advertising method had the additional effect of diminishing the importance of critical reviews, popularising the so-called "critic-proof" status of megamusicals.
Besides Japan, Cats is also produced regularly in other parts of Asia. The region has hosted numerous English-language productions of the musical, beginning with a tour from 1993 to 1994 when it played in Singapore (with local actress Jacintha Abisheganaden as Grizabella), Hong Kong and South Korea. Cats returned to Asia from 2002 to 2004 when it visited Malaysia, South Korea, Shanghai, Taipei and Beijing; the 2004 cast included Slindile Nodangala in the role of Grizabella. A touring company visited Asia again between 2007 and 2010, including stops in Taiwan, Macau, and Thailand in 2007; South Korea from 2007 to 2009; China in 2008; Singapore and Hong Kong in 2009 (with Delia Hannah playing Grizabella); and Manila in 2010 (with Lea Salonga as Grizabella). Cats toured Asia again from 2014 to 2015, making stops in South Korea, Singapore and Macau. Two years later, another international tour was launched and is scheduled to run through 2020, with visits to South Korea from 2017 to 2018, Hong Kong and Taiwan in 2018, China in 2018 (with Joanna Ampil as Grizabella) and 2019, and planned stops in the Philippines and Singapore in 2019, and Malaysia in 2020.
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." 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.
Cats have excellent night vision and can see at only one-sixth the light level required for human vision.:43 This is partly the result of cat eyes having a tapetum lucidum, which reflects any light that passes through the retina back into the eye, thereby increasing the eye's sensitivity to dim light. Another adaptation to dim light is the large pupils of cats' eyes. Unlike some big cats, such as tigers, domestic cats have slit pupils. These slit pupils can focus bright light without chromatic aberration, and are needed since the domestic cat's pupils are much larger, relative to their eyes, than the pupils of the big cats. At low light levels, a cat's pupils will expand to cover most of the exposed surface of its eyes. However, domestic cats have rather poor color vision and (like most nonprimate mammals) have only two types of cones, optimized for sensitivity to blue and yellowish green; they have limited ability to distinguish between red and green. A 1993 paper reported a response to middle wavelengths from a system other than the rods which might be due to a third type of cone. However, this appears to be an adaptation to low light levels rather than representing true trichromatic vision.
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."
Cats and many other animals have a Jacobson's organ in their mouths that is used in the behavioral process of flehmening. It allows them to sense certain aromas in a way that humans cannot. Cats are sensitive to pheromones such as 3-mercapto-3-methylbutan-1-ol, which they use to communicate through urine spraying and marking with scent glands. Many cats also respond strongly to plants that contain nepetalactone, especially catnip, as they can detect that substance at less than one part per billion. About 70–80% of cats are affected by nepetalactone. This response is also produced by other plants, such as silver vine (Actinidia polygama) and the herb valerian; it may be caused by the smell of these plants mimicking a pheromone and stimulating cats' social or sexual behaviors.
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.
There are also several powerhouses who worked behind the scenes of the film. Academy Award-winning director Tom Hopper directed and wrote the screenplay, which is of course based on the stage production — which, in turn, was based on poet T. S. Eliot's "Old Possum's Book of Practical Cats." Hopper also directed best-picture winner "The King's Speech" and the musical-turned-movie "Les Misérables."
Similar to the original London staging, the set of the 1,200-capacity CATS Theatre is built on a revolving stage floor such that during the overture, the stage and sections of the stalls revolve approximately 180 degrees into place. In 1998, the Japanese production underwent major revisions to the choreography, staging and costume designs. Following further revisions in 2018, the current incarnation features 25 named cats, including both Jemima and Sillabub (who have evolved into two separate characters), and an original character named Gilbert.
In 2003, the International Commission on Zoological Nomenclature (ICZN) fixed the scientific name for the wildcat as F. silvestris. The same commission ruled that the domestic cat is a distinct taxon Felis catus. Following results of phylogenetic research, the domestic cat was considered a wildcat subspecies F. silvestris catus in 2007.
